LP38503-ADJ - 3A FlexCap Low Dropout Linear Regulator

Download the LP38503-ADJ datasheet PDF. This datasheet also covers the LP38501-ADJ variant, as both devices belong to the same 3a flexcap low dropout linear regulator family and are provided as variant models within a single manufacturer datasheet.

Description

National's FlexCap LDO's feature unique compensation that allows the use of any type of output capacitor with no limits on minimum or maximum ESR.

The LP38501/3 series of lowdropout linear regulators operates from a +2.7V to +5.5V input supply.

Features

  • FlexCap: Stable with ceramic, tantalum, or aluminum.
  • capacitors Stable with 10 µF input/output capacitor Adjustable output voltage from 0.6V to 5V Low ground pin current 25 nA quiescent current in shutdown mode Guaranteed output current of 3A Available in TO-263, TO-263 THIN packages Guaranteed VADJ accuracy of ±1.5% @ 25°C (A Grade) Guaranteed VADJ accuracy of ±3.5% @ 25°C (STD) Over-Temperature and Over-Current protection.

LP38501/3-ADJ, LP38501A/3A-ADJ 3A FlexCap Low Dropout Linear Regulator for 2.7V to 5.5V Inputs May 19, 2008 LP38501/3-ADJ, LP38501A/3A-ADJ 3A FlexCap Low Dropout Linear Regulator for 2.7V to 5.5V Inputs General Description National's FlexCap LDO's feature unique compensation that allows the use of any type of output capacitor with no limits on minimum or maximum ESR. The LP38501/3 series of lowdropout linear regulators operates from a +2.7V to +5.5V 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. Developed on a CMOS process, (utilizing a PMOS pass transistor), the LP38501/3 has low quiescent current that changes little with load current.
