SA57031-28UK - Low Dropout Linear Regulator

Download the SA57031-28UK datasheet PDF. This datasheet also covers the SA57031-18UK variant, as both devices belong to the same low dropout linear regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The SA57031 is a 150 mA, fixed output voltage regulator designed to provide very low dropout voltage and low noise in battery powered and portable applications.

The output voltage is preset to voltages between 1.8 to 5.0 Volts, in 100 mV increments.

Features

  • Many Preset Output Voltages: 1.8 to 5.0 V in 0.1 V increments.
  • Wafer-level chip scale package (WL-CSP4).
  • Extremely low PSRR: 80 dB typical at 1 kHz.
  • Low Dropout Voltage: 100 mV (typ) @ 50 mA output current.
  • Very Low Consumption Current: 100 mA typ. (when not loaded), 0.1 mA max. (when off).
  • High precision Output Voltage: ±2%.
  • Output Current Capacity: 150 mA (typ).
  • Low Noise: 30mVrms @ 10 Hz to 100 kHz.
  • Good Line Re.
