Analog Devices MAX8532 Product Info

• Guaranteed 200mA Output Current
• Low 100mV (typ) Dropout at 100mA
• Low 40µV_RMS Output Noise
• Low 80µA Operating Supply Current
• 62dB PSRR
• < 1µA Shutdown Current
• Thermal-Overload and Short-Circuit Protection
• Output Current Limit
• Tiny 1.16mm x 1.57mm x 0.66mm UCSP (3 x 2 Grid)

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 (40µV_RMS) and a logic-controlled shutdown input. The device is available in a tiny 6-pin UCSP.
