LP3875-ADJ

1.5A Fast Ultra Low Dropout Linear Regulators

General Description

The LP3875-ADJ fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3875-ADJ is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3875-ADJ to operate under extremely low dropout conditions.

Dropout Voltage: Ultra low dropout voltage; typically 38mV at 150mA load current and 380mV at 1.5A load current.

Ground Pin Current: Typically 6mA at 1.5A load current.

Shutdown Mode: Typically 10nA quiescent current when the shutdown pin is pulled low.

Adjustable Output Voltage: The output voltage may be programmed via two external resistors.

Features

• Ultra low dropout voltage

• Low ground pin current

• Load regulation of 0.06%

• 10nA quiescent current in shutdown mode

• Guaranteed output current of 1.5A DC

• Available in TO-263, TO-220 and SOT-223 packages

• Minimum output capacitor requirements

• Overtemperature/overcurrent protection

• −40˚C to +125˚C junction temperature range

Applications

• Microprocessor power supplies

• GTL, GTL+, BTL, and SSTL bus terminators

• Power supplies for DSPs

• SCSI terminator

• Post regulators

• High efficiency linear regulators

• Battery chargers

• Other battery powered applications

Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.

Note 2: At elevated temperatures, devices must be derated based on package thermal resistance. The devices in TO220 package must be derated at θjA = 50˚C/W (with 0.5in2, 1oz. copper area), junction-to-ambient (with no heat sink). The devices in the TO263 surface-mount package must be derated at θjA = 60˚C/W (with 0.5in2, 1oz. copper area), junction-to-ambient. The SOT-223 package must be derated at θjA = 90˚C/W (with 0.5in2, 1oz. copper area), junction-to-ambient.

Note 3: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.

Note 4: Typical numbers are at 25˚C and represent the most likely parametric norm.

Note 5: Limits are guaranteed by testing, design, or statistical correlation.

Note 6: If used in a dual-supply system where the regulator load is returned to a negative supply, the output must be diode-clamped to ground.

Note 7: The output PMOS structure contains a diode between the VIN and VOUT terminals. This diode is normally reverse biased. This diode will get forward biased if the voltage at the output terminal is forced to be higher than the voltage at the input terminal. This diode can typically withstand 200mA of DC current and 1Amp of peak current.

Note 8: Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the input line voltage. Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in load current.

Note 9: Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the drop-out voltage is nothing but the input to output differential, since the minimum input voltage is 2.5V.

Note 10: The minimum operating value for VIN is equal to either [VOUT(NOM) + VDROPOUT] or 2.5V, whichever is greater.
