Product details
Overview
MIC5330-OGYML-TR from Micrel is a dual-channel ultra-low dropout (ULDO™) linear regulator delivering 300mA per channel with fixed 2.9V/1.8V outputs in an 8-pin 2mm × 2mm MLF® package. It features 75mV dropout at 300mA, 30µVRMS output noise, and >70dB PSRR at 1kHz - engineered for powering RF-sensitive circuitry such as cellular camera modules and imaging sensors.
For engineers reviewing the MIC5330-OGYML-TR datasheet, MIC5330-OGYML-TR pinout, MIC5330-OGYML-TR application, or MIC5330-OGYML-TR equivalent, key selection considerations include independent active-high enable control (EN1/EN2), µCap compatibility with 1µF ceramic output capacitors, thermal shutdown protection, and operation across –40°C to +125°C junction temperature range.
Technical Context
The MIC5330-OGYML-TR integrates two independent CMOS-based ULDO regulators sharing a common input but with separate enable inputs (EN1, EN2) and outputs (VOUT1 = 2.9V, VOUT2 = 1.8V). Each channel maintains ±2% initial output accuracy and exhibits fast 30µs startup time with 0.1µF bypass capacitor on BYP pin.
Its architecture supports no-load stability and low-quiescent-current operation (75µA per output), while thermal shutdown and current-limit protection (350–950mA) ensure robustness under fault conditions. The MLF® package's exposed pad (EP) must be connected to GND for optimal thermal performance and electrical integrity.
Key Specifications

FAQ
What are the fixed output voltages of the MIC5330-OGYML-TR?
The MIC5330-OGYML-TR provides two fixed, non-adjustable output voltages: 2.9V on VOUT1 (Pin 8) and 1.8V on VOUT2 (Pin 7). These values are laser-trimmed during manufacturing and specified with ±2% initial accuracy over temperature. The marking "EOG" on the top-side identifies this specific 2.9V/1.8V variant within the MIC5330 family.
Does the MIC5330-OGYML-TR require external capacitors for stability?
Yes, the MIC5330-OGYML-TR requires a minimum 1µF ceramic capacitor from VIN to GND and a minimum 1µF ceramic capacitor from each VOUT to GND for stability. A 0.1µF capacitor on the BYP pin (Pin 3) is recommended to achieve the specified 30µVRMS output noise and >70dB PSRR. All capacitors must be low-ESR X7R/X5R types.
Can the MIC5330-OGYML-TR operate with no load on either output?
Yes, the MIC5330-OGYML-TR remains stable and in regulation with zero load on either or both outputs - a key differentiator from many competing LDOs. This capability supports applications like CMOS RAM keep-alive circuits or always-on sensor biasing where one rail may be idle while the other is active.
What is the maximum ambient temperature for continuous 300mA operation on both channels of the MIC5330-OGYML-TR?
With a minimum PCB footprint and proper EP-to-GND connection, the MIC5330-OGYML-TR supports continuous 300mA per channel up to an ambient temperature of 62.9°C. This assumes VIN = 3.3V, VOUT1 = 2.9V, VOUT2 = 1.8V, and θJA = 90°C/W. Exceeding this limit triggers thermal shutdown.
How does the BYP pin function in the MIC5330-OGYML-TR?
The BYP pin (Pin 3) connects to the internal voltage reference node. Adding a 0.1µF capacitor from BYP to GND reduces output voltage noise by bypassing reference fluctuations and improves PSRR, especially at higher frequencies. Increasing the BYP capacitance further lowers noise but slightly extends the 30µs startup time.
