LDO Voltage Regulators Dual 300mA micropower ULDO, with POR

Inquiry Add To Bom

MIC5332-SSYMT-TR General Description

The MIC5332 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5332 integrates two high performance 300mA LDOs and a POR generator into a 2mm x 2mm Thin package. This solution occupies the same PC board area of a single SOT-23 package.

The MIC5332 is designed to reject input noise and provide low output noise with fast transient response so as to respond to any load change quickly even though it is a low quiescent current part. This combination of PSRR, low noise and transient response, along with low power consumption makes for a very high performance, yet general purpose product.

The MIC5332 is a μCap design, operating with very small ceramic output capacitors, which reduces required board space and component cost. It is available in fixed output voltages in a tiny 8-pin 2mm x 2mm Thin leadless package.

Excellent compact device!At first, the led was not properly sealed, but the device still worked. Fixed.Neon lamps light when powered by 2.5 walt.Ignition of fluorescent lamps from 9 volts.Burning objects from 12 volts.Large arcs, from 20 volts and above, but... Include not for long! The device is compact, the radiator is small, there is a risk of overheating.I recommend using at voltages 6 .. 10 v. So the device is unlikely to overheat.
