LDO Regulators Provide Low-Voltage Power For Embedded Applications

Dec. 1, 1998
Designed to provide 2.5V or 1.8V at 180 or 500 mA for DSPs, cache memory, and peripherals in low-voltage µP applications, MIC5207 and MIC5209 low-dropout (LDO) voltage regulators are well-suited for battery-operated products where small size and

Designed to provide 2.5V or 1.8V at 180 or 500 mA for DSPs, cache memory, and peripherals in low-voltage µP applications, MIC5207 and MIC5209 low-dropout (LDO) voltage regulators are well-suited for battery-operated products where small size and low-power operation are critical. Quiescent current is a low 80 µA, with both devices also featuring a shutdown pin and boasting of excellent line and load regulation.MIC5207 comes in a small footprint SOT23-5 package, delivers 180 mA, and offers 3% initial tolerance, whereas MIC5209 resides in a SOT-223 or power SO-8 package, puts out 500 mA, has a 1% initial tolerance. In addition, both LDO regulators provide reverse battery protection and current and thermal limiting features.
