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.

The SA57031 achieves excellent performance in all specifications such as excellent power supply ripple rejection at low frequency, low supply-current, low dropout voltage, low power consumption, extremely small size with chip scaled package (CSP), extremely low output noise voltage, very fast start-up response time, precision output, fast dynamic response to line and load regulation, etc. SA57031 consists of an internal voltage reference, and current limit.

The SA57031 is housed in a WL-CSP4 package (see dimensional drawing for layout).
