GENERAL 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. This
regulator consists of an internal voltage reference, and current limit.
The SA57031 is housed in a WL-CSP4 package (see dimensional
drawing for layout).
