Low-Noise, Low-Dropout,
200mA Linear Regulator in UCSP
General Description
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: All units are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 3: The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V.
Specification applies only when VOUT > = 2.5V.
