MIC37100/01/02

1A Low-Voltage µCap LDO Regulator

Features

General Description

• Fixed and Adjustable Output Voltages to 1.24V

The MIC37100, MIC37101, and MIC37102 are 1A low

dropout, linear voltage regulators that provide low

voltage, high current output from an extremely small

package. Utilizing Microchip’s proprietary Super βeta

PNP pass element, the MIC37100/01/02 offers

extremely low dropout (typically 280 mV at 1A) and low

ground current (typically 11 mA at 1A).

• µCap Regulator, 10 µF Ceramic Output Capacitor

Stable

• 280 mV Typical Dropout at 1A

- Ideal for 3.0V to 2.5V Conversion

- Ideal for 2.5V to 1.8V, 1.65V or 1.5V

Conversion

The MIC37100 is a ﬁxed output regulator offered in the

SOT-223 package. The MIC37101 and MIC37102 are

ﬁxed and adjustable regulators, respectively, in a

thermally enhanced power 8-pin SOIC (small outline

package). The MIC37102 is also available in the S-PAK

power package, for applications that require higher

power dissipation or higher operating ambient

temperatures.

• 1A Minimum Guaranteed Output Current

• 1% Initial Accuracy

• Low Ground Current

• Current Limiting and Thermal Shutdown

• Reversed Leakage Protection

• Fast Transient Response

• Low Profile SOT-223 Package

• Power SO-8 Package

The MIC37100/01/02 is ideal for PC add in cards that

need to convert from standard 5V to 3.3V, 3.3V to 2.5V

or 2.5V to 1.8V or lower. A guaranteed maximum

dropout voltage of 500 mV over all operating conditions

allows the MIC37100/01/02 to provide 2.5V from a

supply as low as 3V and 1.8V from a supply as low as

2.3V.

• S-PAK Package (MIC37102 Only)

Applications

• LDO Linear Regulator for PC Add In Cards

• PowerPC Power Supplies

• High Efﬁciency Linear Power Supplies

• SMPS Post Regulator

The MIC37100/01/02 is fully protected with overcurrent

limiting and thermal shutdown. Fixed output voltages of

1.5V, 1.65V, 1.8V, 2.5V and 3.3V are available on

MIC37100/01 with adjustable output voltages to 1.24V

on MIC37102.

• Multimedia and PC Processor Supplies

• Battery Chargers

• Low Voltage Microcontrollers and Digital Logic
