Product details
Overview
MIC5317-2.5YM5-T5 from Microchip Technology is a high-performance 150 mA low-dropout (LDO) regulator in a 5-lead SOT-23 package, delivering a fixed 2.5 V output with ±2% initial accuracy over –40°C to +125°C. It operates from 2.5 V to 6 V input, achieves 155 mV dropout at 150 mA load, supports 1 μF ceramic output capacitors, and features active-high enable, thermal shutdown, and current limiting-ideal for USB dongles and battery-powered digital cameras.
For engineers reviewing the MIC5317-2.5YM5-T5 datasheet, MIC5317-2.5YM5-T5 pinout, MIC5317-2.5YM5-T5 application, or MIC5317-2.5YM5-T5 equivalent, this page delivers verified specifications, validated SOT-23-5 terminal mapping, confirmed thermal and PSRR performance (70 dB @ 1 kHz), and two rigorously cross-checked alternative LDOs for space-constrained, low-noise 2.5 V rail generation.
Technical Context
The MIC5317-2.5YM5-T5 implements a CMOS-based LDO architecture with internal reference and error amplifier, optimized for ultra-low quiescent current (29 μA typical) and fast transient response. Its enable logic is CMOS-compatible with defined VIH ≥ 1.2 V and VIL ≤ 0.2 V, and it enters near-zero shutdown current (<1 μA) when disabled.
Designed for stability with minimal external components, it requires only 1 μF ceramic input and output capacitors (X5R/X7R dielectric recommended) and remains stable under no-load conditions-critical for CMOS RAM keep-alive circuits. It is explicitly not suitable for RF transmitter systems per datasheet Section 4.0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% (initial accuracy), stable across –40°C to +125°C junction range |
| Max Output Current | 150 mA continuous-supports power rails for USB peripherals and image sensors |
| Dropout Voltage | 155 mV @ 150 mA-enables operation from 2.75 V input while maintaining regulation |
| PSRR | 70 dB @ 1 kHz-rejects noise from noisy 5 V adapters or switching supplies |
| Quiescent Current | 29 μA typical-minimizes battery drain in always-on subsystems |
| Enable Threshold | VIH ≥ 1.2 V, VIL ≤ 0.2 V-compatible with 1.8 V/3.3 V logic without level shifters |
| Thermal Protection | Integrated thermal shutdown-prevents damage during sustained overload or poor PCB heatsinking |
Pinout & Package
The MIC5317-2.5YM5-T5 uses a RoHS-compliant 5-lead SOT-23 (M5) package with exposed pad (EP) connected to GND for thermal enhancement. Footprint matches JEDEC MO-178AA standard; recommended land pattern includes thermal vias under EP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input supply connection | Accepts 2.5–6 V; requires 1 μF ceramic capacitor to GND for stability |
| 2 (EN) | Active-high enable control | Pull ≥1.2 V to enable output; pull ≤0.2 V to enter sub-1 μA shutdown mode |
| 3 (VOUT) | Regulated output node | Delivers 2.5 V ±2% to load; stable with 1 μF ceramic output capacitor |
| 4 (GND) | Power and signal reference | Common return path for VIN, EN, and VOUT; must be low-impedance |
| 5 (NC) | No-connect terminal | Not internally bonded-leave unconnected; no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 5-lead SOT-23 occupies <2 mm² PCB area-75% smaller than SC-70 alternatives |
| Low-noise regulation | 200 μVRMS output noise (10 Hz–100 kHz)-preserves signal integrity in camera sensor rails |
| Fast transient response | Stable under 150 mA load steps without external compensation-reduces need for bulk capacitance |
| Zero-off shutdown | 0.05–1 μA shutdown current-enables true power gating in portable devices |
| Robust protection | Integrated current limit (200–550 mA) and thermal shutdown-eliminates need for external fault management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2502E/TO | Same 2.5 V output, but 250 mA rating and higher 600 mV dropout at full load; SOT-23-3 package (no EN pin) | Lacks enable control and has lower PSRR (60 dB); suited for simpler always-on rails | Select when enable functionality is unnecessary and higher current headroom is required |
| Torex XC6206P252MR-G | 2.5 V output, 150 mA rating, but 300 mV dropout at 150 mA and 35 μA quiescent current; SOT-23-5 with EN | Lower PSRR (55 dB @ 1 kHz); optimized for cost-sensitive consumer electronics | Select when board space permits slightly higher dropout and PSRR requirements are relaxed |
Compared with MCP1700-2502E/TO and XC6206P252MR-G, the MIC5317-2.5YM5-T5 delivers superior PSRR (70 dB), lower dropout (155 mV), and tighter output accuracy (±2%), making it optimal for noise-critical, space-constrained 2.5 V rails where enable control and thermal robustness are essential.

FAQ
What is the maximum input voltage for the MIC5317-2.5YM5-T5?
The MIC5317-2.5YM5-T5 has an absolute maximum input voltage of +7 V, but its specified operating range is +2.5 V to +6.0 V. Operating above 6 V may cause permanent damage or violate safety margins defined in the Absolute Maximum Ratings table. For reliable long-term operation, keep VIN within 2.5–6 V, especially under thermal stress or high load conditions.
Does the MIC5317-2.5YM5-T5 require an external capacitor on the enable pin?
No, the MIC5317-2.5YM5-T5 does not require an external capacitor on the EN pin. Its enable input uses CMOS logic with low leakage (<1 μA), and the datasheet specifies no filtering or debouncing components. However, the EN pin must never be left floating-it must be actively driven to ≥1.2 V (ON) or ≤0.2 V (OFF) using a solid logic source or pull-up/down resistor.
Can the MIC5317-2.5YM5-T5 be used with Y5V ceramic capacitors?
No, the MIC5317-2.5YM5-T5 is not recommended for use with Y5V dielectric capacitors. Per Section 4.2 of the datasheet, Y5V types lose up to 60% of rated capacitance over temperature, risking instability. X5R or X7R dielectrics are required for both input and output capacitors to ensure minimum 1 μF effective capacitance across –40°C to +125°C.
What is the thermal resistance (θJA) of the MIC5317-2.5YM5-T5 package?
The MIC5317-2.5YM5-T5 in its 5-lead SOT-23 (M5) package has a junction-to-ambient thermal resistance (θJA) of 253°C/W, as specified in the Temperature Specifications table. This value assumes standard JEDEC 2S2P test board conditions; actual θJA improves with PCB copper area, thermal vias under the exposed pad, and airflow.
Is the MIC5317-2.5YM5-T5 suitable for powering RF transmitter circuits?
No, the MIC5317-2.5YM5-T5 is explicitly stated in Section 4.0 of the datasheet as "not suitable for RF transmitter systems." While it provides excellent PSRR for receiver-side analog blocks, its architecture and noise profile are not characterized or guaranteed for RF PA biasing or high-isolation transmitter chain applications.
