STL6342, 250mA Low Quiescent Current Linear Regulator

FEATURE The STL6342 series is a positive voltage regulator with high accuracy output voltage and ultra-low quiescent current which is typically 2.

Features

* a P-channel MOSFET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive, which reduces quiescent current. PNP
* based regulators also waste considerable current in dropout conditions when the pass transistor saturates, and use high base-d

Applications

* which require low quiescent current. The STL6342 consists of a bandgap reference voltage source, an error amplifier, a P-channel pass transistor, a resistor-divider for setting output voltage, a current limiter, and temperature limit protection circuit. The high-accuracy output voltage is preset at
