Product details
Overview
MIC5365-1.5YC5-TR from Micrel is a fixed-output 1.5V, 150mA low-dropout linear regulator in SC-70-5 package, delivering ±2% initial output accuracy, 155mV dropout at full load, and 29µA quiescent current - optimized for power-sensitive portable electronics such as GPS modules and handheld devices.
For engineers reviewing the MIC5365-1.5YC5-TR datasheet, MIC5365-1.5YC5-TR pinout, MIC5365-1.5YC5-TR application, or MIC5365-1.5YC5-TR equivalent, key selection criteria include input voltage range (2.5V–5.5V), thermal shutdown protection, stability with 1µF ceramic output capacitors, and zero-off-mode current draw (<1µA) during disable.
Technical Context
The MIC5365-1.5YC5-TR uses a CMOS-based pass element with active-high enable control and internal thermal shutdown. It operates across –40°C to +125°C junction temperature and maintains regulation under no-load conditions - critical for CMOS RAM keep-alive circuits.
Its high PSRR (70dB at low frequency, 65dB up to 10kHz) and low output noise (200µVRMS, 10Hz–100kHz) support noise-sensitive analog and RF subsystems. The regulator requires only 1µF input and output ceramic capacitors (X5R/X7R dielectric) for stable operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% initial accuracy; ensures precise biasing for 1.5V logic or analog rails without external feedback. |
| Max Output Current | 150mA guaranteed; supports moderate-power peripherals like GPS baseband ICs or camera sensor interfaces. |
| Dropout Voltage | 155mV @ 150mA; enables operation from 1.65V minimum input - compatible with single-cell Li-ion (3.0–4.2V) via intermediate buck stage. |
| Quiescent Current | 29µA typical; minimizes standby power loss in battery-backed systems with infrequent wake-up cycles. |
| PSRR | 70dB @ ≤1kHz; suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Input Voltage Range | 2.5V to 5.5V; accommodates wide-input sources including USB (5V), boosted coin cells, or multi-cell battery packs. |
| Enable Threshold | Logic-high enable ≥1.2V; compatible with 1.8V/3.3V GPIO without level-shifting. |
Pinout & Package
SC-70-5 package: 1.25mm × 2.1mm footprint, 0.65mm pitch, RoHS-compliant lead finish, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main supply input; must be decoupled with 1µF X5R/X7R ceramic capacitor to ground. |
| 2 | GND | Analog/digital ground reference; connects directly to PCB ground plane for low-noise regulation. |
| 3 | EN | Active-high enable; pulled high to activate regulator; must not float - tie to VIN or host MCU GPIO. |
| 4 | VOUT | Regulated 1.5V output; drives load and requires 1µF ceramic capacitor to ground for stability. |
| 5 | NC | No-connect terminal; internally unconnected - leave unpopulated on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC-70-5 package | 1.25mm × 2.1mm footprint - reduces board area by 75% vs. legacy SOT-23, ideal for space-constrained handhelds. |
| Zero-off-mode current | ≤1µA shutdown current - extends battery life in always-on monitoring applications like wearable health sensors. |
| Stable with 1µF ceramic output cap | Eliminates need for large tantalum or aluminum electrolytics; simplifies BOM and improves reliability. |
| Thermal shutdown & current limit | Internally protects against overtemperature (>150°C) and short-circuit faults (325mA typical current limit). |
| No-load stability | Maintains regulation with 0mA load - essential for maintaining voltage on backup rails for real-time clocks or SRAM. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 150mA, 1.5V fixed, 2.3µA quiescent current, but only 100mV dropout at 250mA - lower IQ but higher dropout at rated load. | Optimized for ultra-low-power IoT sensors; less suitable for high-transient GPS or camera loads due to slower transient response. | Select if standby current is primary concern and load transients are infrequent. |
| Torex XC6206P152MR-G | 150mA, 1.5V fixed, 1µA quiescent current, but 300mV dropout at 150mA and no enable pin - simpler control but poorer efficiency under load. | Suitable for basic always-on rails where enable control and low dropout are non-critical. | Choose when minimal BOM count and lowest possible shutdown current outweigh regulation performance. |
Compared with MCP1700T-1502E/TT and XC6206P152MR-G, the MIC5365-1.5YC5-TR delivers superior transient response and PSRR while maintaining competitive quiescent current - making it optimal for portable RF and imaging systems demanding both low noise and dynamic load capability.

FAQ
What is the maximum input voltage rating for the MIC5365-1.5YC5-TR?
The MIC5365-1.5YC5-TR has an absolute maximum input voltage of 6V, but its specified operating input range is 2.5V to 5.5V. Exceeding 5.5V may cause permanent damage or violate safety margins defined in the datasheet's Absolute Maximum Ratings table. For reliable long-term operation, keep VIN within 2.5V–5.5V and ensure proper input decoupling with a 1µF ceramic capacitor.
Does the MIC5365-1.5YC5-TR include an auto-discharge function?
No, the MIC5365-1.5YC5-TR does not include an auto-discharge function. That feature is exclusive to the MIC5366 variant (e.g., MIC5366-1.5YC5*). The MIC5365-1.5YC5-TR lacks the internal NFET discharge path; when disabled, output voltage decays only through the load and output capacitor leakage - not actively pulled to ground.
Can the MIC5365-1.5YC5-TR operate without an output capacitor?
No, the MIC5365-1.5YC5-TR requires a minimum 1µF ceramic output capacitor (X5R or X7R dielectric) for stability. Operating without it risks oscillation or regulation failure. Unlike some older LDOs, it is not no-capacitor stable - the design relies on this capacitance for phase margin and transient response control per the Application Information section.
What is the thermal resistance (θJA) of the MIC5365-1.5YC5-TR in its SC-70-5 package?
The junction-to-ambient thermal resistance (θJA) for the MIC5365-1.5YC5-TR in SC-70-5 package is 256.5°C/W, as specified in the Electrical Characteristics table. This value assumes standard JEDEC test board conditions; actual θJA in end equipment depends on PCB copper area, layer stack-up, and airflow - design guidelines recommend maximizing GND copper under the package for improved heat dissipation.
Is the MIC5365-1.5YC5-TR RoHS-compliant and halogen-free?
Yes, the MIC5365-1.5YC5-TR is RoHS-compliant and features a lead-free (Pb-free) finish. Per the Ordering Information notes, all MIC5365/6 variants - including the SC-70-5 package - use NiPdAu lead finish and halogen-free mold compound, meeting both RoHS Directive 2011/65/EU and JEDEC JS709 requirements.
