MIC2920A-12BS Détails du produit

General Description

The MIC2920A family are “bulletproof,” efficient voltage regulators with very low dropout voltage (typically 40mV at light loads and 370mV at 250mA), and very low quiescent current (140µA typical). The quiescent current of the MIC2920A in creases only slightly in dropout, prolonging battery life. Key MIC2920A features include protection against reversed bat tery, fold-back current limiting, and automotive “load dump” protection (60V positive transient).



Features

• High output voltage accuracy

• Guaranteed 400mA 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

• Error flag warns of output dropout

• Logic-controlled electronic shutdown

• Output programmable from 1.24V to 26V (MIC29202/MIC29204)

• Available in TO-220-3, TO-220-5, and surface-mount TO-263-5, SOT-223, and SO-8 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-regulators

• Voltage reference

• High-efficiency linear power supplies
