Overview

PAM3101 300mA High PSRR Low Dropout CMOS Linear Regulator Features www.
datasheet4u.
com (V =3.
3V) General Description The PAM3101 series of positive voltage linear regulators feature low quiescent current (65 μ A Typ.
) and low dropout voltage, making them ideal for battery powered applications.
Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed.
Space-saving SOT-23, SOT-89 and SC70 packages are attractive for portable and handheld applications.
They have both thermal shutdown and current limit features to prevent device failure from extreme operating conditions.
They are stable with an output capacitor of 2.
2 μ F or greater.
