Microchip Technology MIC2940A-3.3BU
- Part Number:
- MIC2940A-3.3BU
- Manufacturer:
- Microchip Technology
- Ventron No:
- 3766483-MIC2940A-3.3BU
- Description:
- IC REG LDO 3.3V 1.25A TO263-3
- ECAD Model:
-
- Datasheet:
- MIC2940A-3.3BU
Description
The MIC2940A and MIC2941A are efficient voltage regulators with low dropout voltage (40mV at light loads, 350mV at 1A) and low quiescent current (240μA typical). The MIC2940A's quiescent current increases slightly in dropout, extending battery life.
Features
High output voltage accuracy
Guaranteed 1.25A output
Low quiescent current
Low dropout voltage
Extremely tight load and line regulation
Very low temperature coefficient
Current and thermal limiting
Input withstands -20V reverse battery and 60V positive transients
Logic-controlled electronic shutdown
Output programmable from 1.24V to 26V (MIC2941A)
Available in TO-220, TO-263, TO-220-5, and TO-263-5 packages
Applications
Battery powered equipment
Cellular telephones
Laptop, notebook, and palmtop computers
PCMCIA VCC and VPP regulation/switching
Bar code scanners
Automotive electronics
SMPS post-regulator/DC-to-DC modules
Voltage reference
High efficiency linear power supplies
