Product details
Overview
MIC5306-2.8YD5 from Microchip Technology is a 150 mA micropower low-dropout linear regulator with fixed 2.8 V output, 16 μA quiescent current, 45 mV dropout at 100 mA, ±1.0% initial voltage accuracy, and TTL-compatible enable input - designed for battery-powered portable electronics requiring stable, ultra-low-power supply rails.
For engineers reviewing the MIC5306-2.8YD5 datasheet, MIC5306-2.8YD5 pinout, MIC5306-2.8YD5 application, or MIC5306-2.8YD5 equivalent, key selection considerations include dropout performance at light-to-moderate loads, thermal behavior in TSOT-23-5, ground current vs. temperature, PSRR at 10 Hz–1 kHz, and compatibility with 1 μF ceramic output capacitors.
Technical Context
The MIC5306-2.8YD5 implements a CMOS-based LDO architecture with internal reference, error amplifier, and pass transistor - optimized for fast transient response and high PSRR (62 dB @ 10 Hz–1 kHz) while maintaining ultra-low IQ. Its μCap design eliminates need for large bulk capacitance.
It features active-high TTL/CMOS-compatible EN pin (logic low ≤0.2 V, logic high ≥1.0 V), thermal shutdown at 150°C with 15°C hysteresis, and current limiting at 285 mA (typical). The NC pin (Pin 4) is unconnected and must not be bonded or routed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±1.0% (initial), ±2.0% over –40°C to +125°C - ensures stable core/logic rail for baseband processors. |
| Max Output Current | 150 mA continuous - sufficient for powering co-processors, RF front-end bias, or sensor subsystems. |
| Dropout Voltage | 45 mV @ 100 mA - enables operation from single-cell Li-ion (3.0 V min) or 3.3 V rails with minimal headroom loss. |
| Quiescent Current | 16 μA operating, 0.01 μA shutdown - extends battery life in standby/sleep modes of portable devices. |
| PSRR | 62 dB @ 10 Hz–1 kHz - suppresses ripple from switching converters feeding VIN, critical in mixed-signal baseband designs. |
| Stability | Stable with ≥1 μF ceramic capacitor (ESR < 300 mΩ) - reduces BOM cost and PCB area vs. tantalum/aluminum alternatives. |
| Enable Threshold | VIL ≤ 0.2 V, VIH ≥ 1.0 V - interoperable with standard logic families without level-shifting. |
Pinout & Package
Package: 5-Lead Thin SOT-23 (TSOT-23-5), 1.6 mm × 1.6 mm × 0.55 mm profile, RoHS-compliant matte tin finish, thermal resistance θJA = 235°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Supply input | Accepts 2.25 V to 5.5 V input; requires 1 μF bypass capacitor to GND if >10-inch trace or battery-fed. |
| GND (Pin 2) | Ground reference | Low-impedance return path for load and quiescent current; must be connected directly to system ground plane. |
| EN (Pin 3) | Enable control | Active-high logic input; drives regulator into zero-current shutdown when ≤0.2 V; tie to VIN if always-on operation required. |
| NC (Pin 4) | No connect | Internally unconnected; must remain floating - no PCB trace or solder mask opening required. |
| OUT (Pin 5) | Regulated output | Delivers 2.8 V ±1% to load; requires ≥1 μF ceramic capacitor to GND for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| μCap ceramic-stable operation | Enables use of compact, low-cost 1 μF X5R/X7R ceramics instead of larger tantalum or aluminum electrolytics. |
| Ultra-low dropout | 25 mV @ 50 mA and 45 mV @ 100 mA - preserves usable battery capacity down to 2.825 V input at full load. |
| Thermal shutdown with hysteresis | Triggers at 150°C junction temperature with 15°C recovery margin - prevents latch-up during sustained overload or poor heatsinking. |
| Fast turn-on time | 250–500 μs (90% rise) - supports rapid power sequencing in multi-rail systems without external timing delays. |
| Low output noise | 91 μVRMS (10 Hz–100 kHz) - minimizes interference in sensitive analog sections like ADC references or RF synthesizers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2802E/TT | Same 2.8 V output, 250 mA rating, but higher IQ (1.6 μA vs. 16 μA), lower PSRR (50 dB @ 1 kHz), and no thermal hysteresis. | Preferred where higher output current is needed but ultra-low IQ is secondary; less suitable for long-duration battery standby. | Select MIC5306-2.8YD5 when <20 μA IQ and 62 dB PSRR are mandatory; choose MCP1700T-2802E/TT only if 250 mA output is required and thermal hysteresis is non-critical. |
| TCS2117-2800MV | 2.8 V output, 150 mA, 25 μA IQ, but wider input range (1.8–6.0 V) and no enable pin - lacks programmable shutdown capability. | Better suited for always-on industrial sensors; unsuitable for systems requiring dynamic power gating or logic-controlled sequencing. | Choose MIC5306-2.8YD5 when EN functionality and tighter voltage accuracy (±1.0%) are required; TCS2117-2800MV fits simpler, fixed-enable applications with broader VIN tolerance. |
Compared with MCP1700T-2802E/TT and TCS2117-2800MV, the MIC5306-2.8YD5 uniquely balances ultra-low IQ (16 μA), high PSRR (62 dB), precise enable control, and thermal hysteresis - making it optimal for battery-constrained portable baseband and sensor subsystems demanding both efficiency and reliability.

FAQ
What is the maximum input voltage rating for the MIC5306-2.8YD5?
The MIC5306-2.8YD5 has an absolute maximum input voltage (VIN) rating of +6 V. However, its recommended operating input voltage range is +2.25 V to +5.5 V. Exceeding 5.5 V may cause permanent damage or unreliable operation, even if below the 6 V absolute limit. Always maintain VIN within the operating range for guaranteed performance and reliability of the MIC5306-2.8YD5.
Does the MIC5306-2.8YD5 require an external output capacitor, and what type is recommended?
Yes, the MIC5306-2.8YD5 requires an external output capacitor between OUT and GND for stability. Microchip specifies a minimum of 1 μF ceramic capacitor with ESR < 300 mΩ and resonant frequency > 1 MHz. X5R or X7R dielectrics are preferred; ultra-low-ESR types may cause oscillation. The MIC5306-2.8YD5 is designed as a μCap regulator - enabling small-footprint, low-cost ceramic solutions instead of larger tantalum or aluminum alternatives.
What is the typical ground pin current of the MIC5306-2.8YD5 under full load?
The typical ground pin current (IGND) of the MIC5306-2.8YD5 is 16 μA at no load and increases to ≤30 μA across the full 0–150 mA output current range at VIN = 5.5 V. This ultra-low, nearly flat ground current profile contributes directly to the device's micropower efficiency - a defining characteristic of the MIC5306-2.8YD5 in battery-sensitive applications.
Can the MIC5306-2.8YD5 be used without connecting the EN pin?
Yes, the MIC5306-2.8YD5 can operate without an external EN signal by connecting Pin 3 (EN) directly to VIN. This configures the device for always-on operation. Leaving EN floating is prohibited - it must be either actively driven or tied to VIN/GND. The MIC5306-2.8YD5 will not function reliably if EN is unconnected, as the internal logic state becomes undefined.
What thermal protection features does the MIC5306-2.8YD5 include?
The MIC5306-2.8YD5 integrates thermal shutdown that activates at +150°C junction temperature, with 15°C hysteresis for safe recovery. It also includes current limiting (285 mA typical) to prevent excessive power dissipation. These protections work together to safeguard the MIC5306-2.8YD5 during overload, short-circuit, or inadequate PCB thermal relief - ensuring robust operation in compact portable layouts.
