Overview

Features and Benefits

  • 350 mA maximum output current
  • Input voltage supply range
    VBIAS = 2.3 V to 5.5 V
    VIN = 1.2 V to 3.6 V
    2.3 V < VIN < 3.6 V, VIN can be tied to VBIAS
  • Very low dropout voltage: 17 mV @ 100 mA load
  • Low quiescent current: 25 μA @ no load
  • Low shutdown current: <1 μA
  • ±1% accuracy @ 25°C
  • Excellent PSRR performance: 70 dB @ 10 kHz
  • Excellent load/line transient response
  • Optimized for small 1 μF ceramic capacitors
  • Current limit and thermal overload protection
  • Logic controlled enable
  • 5-lead TSOT package

Product Details

The ADP130 is a low quiescent current, low dropout linear regulator. It is designed to operate in dual-supply mode with an input voltage as low as 1.2 V to increase efficiency and provide up to 350 mA of output current. The low 17 mV dropout voltage at a 100 mA load improves efficiency and allows operation over a wider input voltage range.

A dual-supply power solution typically improves conversion efficiency over a single-supply solution because the higher VBIAS supply powers the part, and the lower VIN supply delivers current to the load. The power dissipated in the device is thereby reduced. The ADP130 is optimized for stable operation with small 1 μF ceramic output capacitors. The ADP130 delivers good transient performance with minimal board area.

The ADP130 is available in fixed output voltages ranging from : 0.80 V to 3.0 V.

The ADP130 has a typical internal soft start time of 200 μs. Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP130 is available in a tiny 5-lead TSOT package for the smallest footprint solution to meet a variety of portable power applications.
