SA57031-18UK - Micropower 150 mA, Low Noise, Low Dropout Linear Regulator On/Off
The SA57031 is a 150 mA, fixed output voltage regulator designed to provide very low dropout voltage and low noise battery power and portable applications. The output voltage is preset to a voltage between 1.8 and 5.0 volts in 100 mV increments. SA57031 achieves outstanding performance in all specifications such as excellent power supply ripple rejection at low frequency, low supply current, low dropout, low power consumption, very small chip scale package size (CSP), extremely low output noise voltage, very fast startup speed Response time, precision output line and load regulation, fast dynamic response, etc., this regulator includes an internal reference voltage and current limit. SA57031 is housed in the WL-CSP4 package.
