Product details
Overview
MIC5367-1.2YMT-TR from Micrel is a high-performance 150mA continuous / 200mA peak low-dropout linear regulator delivering 1.2V output with ±2% initial accuracy, 180mV dropout at 150mA, and 29µA quiescent current in a 1.6mm × 1.6mm Thin MLF® package. It serves as a precision power supply for noise-sensitive core logic in portable electronics, supporting stable operation from 2.5V–5.5V input.
For engineers reviewing the MIC5367-1.2YMT-TR datasheet, MIC5367-1.2YMT-TR pinout, MIC5367-1.2YMT-TR application, or MIC5367-1.2YMT-TR equivalent, this LDO offers verified PSRR of 65dB at 1kHz, zero-off-mode shutdown (≤1µA), thermal/overcurrent protection, and guaranteed stability with 1µF ceramic output capacitors - critical for battery-powered mobile and handheld designs.
Technical Context
The MIC5367-1.2YMT-TR employs a CMOS-based pass transistor architecture optimized for ultra-low ground current and fast load transient response. Its internal reference and error amplifier deliver tight output regulation across –40°C to +125°C junction temperature, with line regulation of 0.02% typical and load regulation of 0.3% over 100µA–150mA.
Unlike the MIC5368 variant, the MIC5367-1.2YMT-TR lacks auto-discharge circuitry; its EN pin enables active-high control only. The device achieves 65dB power supply rejection up to 1kHz and maintains stability without external compensation due to internal compensation network tuned for 1µF ceramic output capacitance.
Key Specifications

FAQ
What is the maximum output current rating for the MIC5367-1.2YMT-TR?
The MIC5367-1.2YMT-TR provides 150mA continuous output current and supports 200mA peak current for short-duration loads. This rating is valid across the full –40°C to +125°C junction temperature range when used with proper PCB thermal design, including soldering the exposed pad (EP) to a thermal plane.
Does the MIC5367-1.2YMT-TR include an auto-discharge function?
No, the MIC5367-1.2YMT-TR does not include auto-discharge circuitry. That feature is exclusive to the MIC5368 variant (e.g., MIC5368-1.2YMT). The MIC5367-1.2YMT-TR disables cleanly with ≤1µA shutdown current but leaves the output capacitor charged until external discharge occurs.
What capacitor values and types are required for stable operation of the MIC5367-1.2YMT-TR?
The MIC5367-1.2YMT-TR requires a minimum 1µF X7R or X5R ceramic capacitor on both input (VIN–GND) and output (VOUT–GND). Y5V and Z5U dielectrics are not recommended due to excessive capacitance loss over temperature. The device remains stable with no load and does not require ESR tuning.
Can the MIC5367-1.2YMT-TR operate from a 2.5V input while delivering 1.2V at 150mA?
Yes - the MIC5367-1.2YMT-TR has a dropout voltage of 180mV at 150mA, so it regulates properly with a minimum input of 1.38V. At 2.5V input, it operates well within specification, delivering full 150mA with ample headroom and low thermal stress (PD ≈ 180mW).
Is the MIC5367-1.2YMT-TR RoHS compliant and lead-free?
Yes, the MIC5367-1.2YMT-TR uses a Pb-free NiPdAu lead finish and halogen-free mold compound, meeting RoHS Directive 2011/65/EU. The "-TR" suffix denotes tape-and-reel packaging compliant with J-STD-020 moisture sensitivity level 1 (unlimited floor life at <30°C/60% RH).
