MCP1722

High Voltage LDO with Dual Output

and Extended Temperature Range

Key Features

Description

• AEC-Q100, Grade 0 Qualified, PPAP Capable

• Input Voltage Range: 4.5V to 55V

MCP1722 is a dual output, high voltage, low dropout

(LDO) regulator, designed to supply a µProcessor with

either 3.3V or 5.0V. It has a current capability of 100

mA, while also providing 10V or 12V to a motor driver

with a current capability of 50 mA. These specifications

make it ideal for handheld power tools with 20V battery

packs.

- Undervoltage Lock Out (UVLO) 2.7V Typical

• 65V Load Dump Protected (ISO 7637-2/2004)

• Extended Junction Temperature Range: -40°C to

+150°C

• Standard Output Regulated Voltages (V_R):

- V_OUT1: 10V or 12V

MCP1722 comes with Power Good indicators (two

pins, PWG₁and PWG₂) for both outputs and shutdown

functionality (a single SHDN pin) that places the part in

a low current consumption state, of only 4 µA.

- V_OUT2: 3.3V or 5.0V

- Tolerance +/- 2% for each LDO Output

• Output Current Capability Typical:

- V_OUT1: 50 mA

The device comes in two 8-lead VDFN or SOIC

packages, both with exposed pads, for improved

thermal dissipation. While in operation, MCP1722 is

fully protected by thermal shutdown protection and

current foldback limiting.

- V_OUT2: 100 mA

• Open-Drain Power Good Pins for Both LDO

Outputs

• Low Quiescent Supply Current: 50 µA

• Low Shutdown Quiescent Supply Current: 4 µA

• Stable with Ceramic Output Capacitor: 3.3 µF

• Short Circuit Current Foldback Protection

• Thermal Shutdown Protection: 178°C Typical

• High PSRR:
