STL6119 - Fast Transient Response LDO

Datasheet Summary

Description

The STL6119 is a 500mA low noise and fast transient response liner regulator with adjustable output voltage and ultra-low dropout voltage.

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. PNPbased regulators also waste considerable current in dropout when the pass transistor saturates, and use high base-drive currents under large loads. The STL6119 does not suffer from these problems and consumes only 40μA (Typ. ) of current consumption under heavy loads as well as in dropout conditions.
  • Enable Function EN pin starts.

STL6119 500mA Low noise, High PSRR, Fast Transient Response LDO ■DESCRIPTION ■FEATURE The STL6119 is a 500mA low noise and fast transient response liner regulator with adjustable output voltage and ultra-low dropout voltage. Its output voltage is programmed by a resistor divider, and can be as low as 0.8V, which satisfies the most advanced ICs which may require supply voltage to be 0.9V –1.2V. SMC6118 is consists of a precise voltage reference, an error amplifier, a compensation network and alow ON-resistance power P-MOSFET. It also integrates many protection circuitry, like current limit and over-temperature protection module.
