Product details
Overview
MIC5295-3.0YD-TR from Micrel is a fixed 3.0V, 150mA low-dropout linear regulator with ultra-low 18µA ground current, 300mV dropout at full load, and ±1.0% output accuracy-designed for USB power rails and portable electronics powered by 1–3-cell Li-ion batteries.
For engineers reviewing the MIC5295-3.0YD-TR datasheet, MIC5295-3.0YD-TR pinout, MIC5295-3.0YD-TR application, or MIC5295-3.0YD-TR equivalent, this page delivers verified package mapping (TO-252-5), enable-controlled shutdown behavior, reverse battery protection, thermal shutdown, and stability with 2.2µF ceramic output capacitors-key selection criteria for battery-sensitive designs.
Technical Context
The MIC5295-3.0YD-TR implements a µCap LDO architecture stable with ceramic or tantalum output capacitors ≥2.2µF and supports input voltages from 2.3V to 24V. Its active-high EN pin enables precise system-level power sequencing and zero-current shutdown mode.
It integrates reverse battery protection, reverse leakage protection, thermal shutdown, and current limiting (350–500mA). The fixed-output variant eliminates external feedback resistors and delivers 3.0V ±1.0% over –40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1.0% - ensures stable logic supply for microcontrollers and USB peripherals without calibration. |
| Max Output Current | 150mA continuous - sufficient for low-power MCU cores, sensors, and interface ICs in portable systems. |
| Dropout Voltage | 300mV at 150mA - enables operation down to VIN = 3.3V, supporting single-cell Li-ion (3.0–4.2V) with margin. |
| Ground Current | 18µA at light load - extends battery life in keep-alive or standby modes (e.g., RTC or SRAM backup). |
| Input Voltage Range | 2.3V to 24V - accommodates 1–3-cell Li-ion, automotive transients, and industrial 12/24V rails. |
| PSRR | 50dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Output Noise | 47µVRMS (10Hz–100kHz) - suitable for noise-sensitive analog circuitry like ADC references or RF bias rails. |
Pinout & Package
Supplied in PowerTO-252-5 (D-Pak) package with exposed thermal pad for enhanced heat dissipation; θJA = 50°C/W; rated for –40°C to +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | Active-high logic control: <0.4V = shutdown (≈0.1µA IQ); >2.0V = enabled; must not float. |
| 2 - VIN | Supply input | Accepts 2.3–24V; requires ≥1µF input capacitor if remote from source; withstands –20V reverse polarity. |
| 3 - GND | Ground reference | Common return path for input, output, and enable; connects to thermal pad for thermal performance. |
| 4 - VOUT | Regulated output | Delivers stable 3.0V; requires ≥2.2µF ceramic output capacitor (X7R/X5R, ESR ≤3Ω) for stability. |
| 5 - NC | No connect | Not bonded internally; electrically isolated; no routing or connection required on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 18µA typical at 100µA load - enables multi-year battery life in always-on sensor nodes. |
| Reverse battery protection | Blocks reverse current flow when VIN is negative relative to GND - prevents damage during battery insertion errors. |
| Zero-current shutdown | 0.1µA max ground current when EN = 0V - eliminates parasitic drain in off-state systems. |
| Low-ESR capacitor compatibility | Stable with 2.2µF X7R ceramic (ESR ≤3Ω) - avoids costly tantalum and simplifies BOM. |
| Thermal & current protection | Auto-recovering thermal shutdown + foldback current limit - ensures robustness under overload or ambient extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 300mA output, 1.6µA IQ, but only 6V max input - lacks MIC5295-3.0YD-TR's 24V capability and reverse protection. | Suitable for low-power MCU core supplies where input voltage stays below 6V; not viable for automotive or multi-cell battery inputs. | Select when ultra-low IQ dominates and input voltage is constrained; verify absence of reverse-battery risk. |
| TPS76330DBVR | 150mA, 3.0V fixed, 85µA IQ, 300mV dropout, but no reverse battery or reverse leakage protection. | Acceptable for consumer portable devices with controlled battery insertion; unsuitable where reverse polarity exposure is possible. | Choose for cost-sensitive designs where protection features are managed externally; confirm thermal derating at high VIN–VOUT delta. |
Compared with MCP1700T-3002E/TT and TPS76330DBVR, the MIC5295-3.0YD-TR uniquely combines 24V input tolerance, reverse battery protection, and 18µA quiescent current - making it the only option among the three qualified for unregulated automotive or multi-cell Li-ion keep-alive rails without added protection circuitry.

FAQ
What is the minimum input voltage required for MIC5295-3.0YD-TR to regulate 3.0V output?
The MIC5295-3.0YD-TR requires a minimum input voltage of 3.3V to maintain regulation at full 150mA load, based on its 300mV dropout specification. At lighter loads, dropout drops to 45mV (100µA), allowing regulation down to ~3.045V input. Operation below the dropout threshold results in pass-through behavior with no regulation.
Does MIC5295-3.0YD-TR require an external feedback network?
No. The MIC5295-3.0YD-TR is a fixed-output variant with internal resistor divider set to 3.0V; no external feedback components are needed. Only the EN, VIN, GND, and VOUT pins are functional - Pin 5 is NC and must remain unconnected.
Can MIC5295-3.0YD-TR be used with a 2.2µF Y5V ceramic capacitor?
While the MIC5295-3.0YD-TR is stable with 2.2µF output capacitance, Y5V dielectrics lose up to 60% capacitance over temperature and voltage. To ensure ≥2.2µF minimum across –40°C to +125°C and rated voltage, X7R or X5R ceramics are strongly recommended per the datasheet.
What happens to MIC5295-3.0YD-TR if the EN pin is left floating?
If the EN pin is left floating, the MIC5295-3.0YD-TR enters an indeterminate state - output may oscillate, remain partially enabled, or fail to start. The datasheet explicitly requires pull-up or pull-down biasing; a 100kΩ pull-up to VIN is standard practice to guarantee reliable enable behavior.
Is MIC5295-3.0YD-TR compatible with lead-free reflow soldering profiles?
Yes. The TO-252-5 package of MIC5295-3.0YD-TR is rated for standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260°C. Thermal pad soldering is recommended to meet θJA = 50°C/W specification and ensure reliable power dissipation at 150mA.
