MAX8532:Low-Noise, Low-Dropout, 200mA Linear Regulator in UCSP

The MAX8532 offers the benefits of low-dropout voltage and ultra-low power regulation in a subminiaturized UCSP, making it ideal for space-restricted portable equipment. The device operates from a 2.5V to 6.5V input and delivers up to 200mA, with low dropout of 100mV (typ) at 100mA. Designed with an internal P-channel MOSFET pass transistor, the supply current is kept at a low 80µA, independent of the load current and dropout voltage. Other features include short-circuit protection and thermal-shutdown protection. The MAX8532 includes a reference bypass pin for low output noise (40µVRMS) and a logic-controlled shutdown input. The device is available in a tiny 6-pin UCSP.
