... Integrated over-temperature and over-current protec- tion circuitry switches the devices off in case of thermal overload or output short-circuit conditions. The AS1353/AS1356 are optimized for low equivalent- series resistance (ESR) output capacitors. Additionally, all devices contain reversed battery protection which dis- connects the internal circuitry and parasitic diodes if the battery is connected incorrectly ...

... Data Sheet - Detailed Description The AS1353/AS1356 are low-dropout, low-quiescent-current linear regulators intended for LDO regulator applications where output current load requirements range from no load to 150mA. All devices come standard with fixed output volt- ages of 1.5 to 3.6V (see Ordering Information on page Figure 12. Block Diagram ...

... Power Supply Rejection Ratio The AS1353/AS1356 are designed to deliver low dropout voltages and low quiescent currents. Power-supply rejection is 60dB (typ) at low frequencies. To improve power supply-noise rejection and transient response, increase the values of the input and output bypass capacitors (see Figure 13) ...
