STL6341 - 100mA Ultra Low Quiescent Current Linear Regulator

Datasheet Summary

Description

The STL6341 series is a positive voltage regulator with high accuracy output voltage and ultra-low quiescent current which is typically 1.0μA.

The device is ideal for battery powered handheld equipments which require low quiescent current.

Features

  • a P-channel MOSFET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive, which reduces ground pin current. PNPbased regulators also waste considerable current in dropout conditions when the pass transistor saturates, and use high base-drive currents under large loads. The STL6341 does not suffer from these problems and consumes only 1.0μA (Typ. ) of ground pin current under heavy loads as well as in dropout conditions.
  • Output Voltage Se.

Low IQ Regulator STL6341 100mA Ultra Low Quiescent Current Linear Regulator ■DESCRIPTION ■FEATURE The STL6341 series is a positive voltage regulator with high accuracy output voltage and ultra-low quiescent current which is typically 1.0μA. The device is ideal for battery powered handheld equipments which require low quiescent current. The STL6341 contains a bandgap voltage reference, an error amplifier, a P-channel pass transistor, and a resistor-divider for setting output voltage. The output voltage is fixed with high accuracy by advanced trimming technology. The STL6341 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 1.0μF. The devices are available in SOT-23, SOT-89.
