MIC5232-3.3YD5-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5232-3.3YD5-TR is a fixed-output low-dropout linear regulator manufactured by Microchip Technology, providing a stable 3.3V output with a maximum current capability of 10mA. It operates within an input voltage range of 2.7V to 7.0V and features an ultra-low quiescent current of 1.8µA during operation. The device incorporates reverse battery protection, limiting reverse leakage to 20nA when the output voltage exceeds the input voltage. It utilizes a µCap design that ensures stability with small ceramic output capacitors as small as 0.47µF. The component is housed in a lead-free thin SOT-23-5 package and supports an operating junction temperature range from -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'YD5' confirms the TSOT-23-5 package type and lead-free finish. Ensure the ordering code matches the required 3.3V fixed output variant. Confirm the manufacturer designation aligns with Microchip Technology or authorized Micrel legacy sources. Validate RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring minimal ground current and compact board space. The 10mA output limit suits low-power keep-alive circuits rather than high-load digital logic. Verify that the input voltage remains within the specified 2.7V to 7.0V operational window. Consider the thermal resistance characteristics if ambient temperatures approach the upper operating limit.
