PAM3102
DUAL 150mA HIGH PSRR LOW-DROPOUT CMOS REGULATOR
Description
The dual LDO PAM3102 series of positive voltage linear regulators
feature high output voltage accuracy, low quiescent current and low
dropout voltage, making them ideal for battery powered applications.
The line transient response and load transient response are excellent.
Their high PSRR make them useful in applications where AC noise
on the input power supply must be suppressed. Space-saving
SOT23-6 package for 2-ch LDOs is attractive for portable and
handheld applications. They have both thermal shutdown and a
current limit feature to prevent device failure under extreme operating
conditions. They are stable with an output capacitance of 2.2μF or
greater.
