Product details
Overview
MCP1711T-22I/5X from Microchip Technology is a 2.2V fixed-output, ultra-low-quiescent-current (600 nA typical) CMOS low-dropout (LDO) voltage regulator in a 5-lead SOT-23 package, delivering up to 150 mA output current with ±1% output accuracy and 0.37 V typical dropout at 50 mA. It supports input voltages from 1.4V to 6.0V and operates across –40°C to +85°C for industrial battery-powered systems.
For engineers reviewing the MCP1711T-22I/5X datasheet, MCP1711T-22I/5X pinout, MCP1711T-22I/5X application, or MCP1711T-22I/5X equivalent, key selection criteria include shutdown current (10 nA), capacitorless stability, COUT auto-discharge capability, and thermal performance on minimal-copper PCBs.
Technical Context
The MCP1711T-22I/5X implements a PMOS pass transistor architecture with internal error amplifier, current foldback protection, and dedicated SHDN-controlled discharge transistor. Its feedback network is internally trimmed for 2.2V output, eliminating external resistors.
It features true current foldback limiting (80 mA typical short-circuit foldback), active COUT discharge during shutdown (via 450 Ω typical RDCHG), and robust line regulation (±0.01%/V typical) - all enabled without requiring an output capacitor, though ceramic COUT improves transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.2 V with ±1% accuracy at +25°C - ensures stable rail for 2.2V logic or analog circuitry without trimming. |
| Quiescent Current | 600 nA typical - enables multi-year operation from coin cells in energy-harvesting or IoT sensor nodes. |
| Max Output Current | 150 mA - sufficient to power microcontrollers, RF transceivers, or small displays in portable devices. |
| Dropout Voltage | 0.37 V typical at 50 mA - allows regulation from single-cell Li-ion (3.0V min) down to 2.57V input. |
| Shutdown Current | 10 nA typical - reduces system standby power to near-zero when host MCU asserts SHDN. |
| Operating Temp | –40°C to +85°C - qualified for industrial ambient environments without derating. |
| Thermal Resistance | θJA = 400 °C/W on minimal-copper PCB - defines safe power dissipation limits for compact layouts. |
Pinout & Package
Package: 5-Lead SOT-23 (JEDEC MO-178AA), 2.9 mm × 1.6 mm × 1.1 mm body, with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Unregulated input supply | Accepts 1.4V–6.0V; requires low-impedance source; 0.1 µF ceramic input cap recommended for stability. |
| VOUT | Regulated 2.2V output | Capacitorless stable; supports low-ESR ceramic COUT for improved load transient response. |
| GND | Ground reference | Common return for input/output caps and load; referenced by internal error amplifier. |
| SHDN | Active-high enable control | Logic high (>0.91 V) enables regulator; logic low (<0.38 V) disables output and activates COUT discharge. |
| NC | No-connect | Not internally bonded; must be left floating or tied to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitorless operation | Stable with zero output capacitance - eliminates BOM cost and board space for COUT in ultra-low-power sleep modes. |
| COUT auto-discharge | Internal 450 Ω discharge path pulls VOUT to GND within microseconds of SHDN assertion - prevents backfeeding or latch-up in multi-rail systems. |
| True current foldback | Reduces output current to ~80 mA at near-zero VOUT during overload - protects device and source under sustained short-circuit conditions. |
| Ultra-low shutdown current | 10 nA typical - enables <1 µA total system standby current when paired with low-IQ MCUs. |
| Industrial temperature range | –40°C to +85°C operation without derating - suitable for automotive cabin modules and outdoor sensor enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6206P222MR-G | 2.2V fixed, 150 mA, 1 µA IQ, SOT-23-5 - lacks SHDN and COUT discharge. | No enable control or fast discharge; unsuitable for systems requiring clean power sequencing. | Select when only basic regulation is needed and shutdown functionality is handled externally. |
| Richtek RT9013-22GB | 2.2V fixed, 500 mA, 2.5 µA IQ, SOT-23-5 - higher IQ and no COUT discharge. | Higher output current but 4× higher quiescent current; no integrated discharge path. | Choose for higher-current loads where 600 nA IQ is not critical and external discharge is acceptable. |
Compared with XC6206P222MR-G and RT9013-22GB, the MCP1711T-22I/5X uniquely combines nanoscale quiescent current, integrated SHDN-controlled discharge, and capacitorless stability - making it optimal for energy-constrained, multi-rail, or fast-wake systems where power integrity and sequencing matter.

FAQ
What is the maximum input voltage rating for the MCP1711T-22I/5X?
The MCP1711T-22I/5X has an absolute maximum input voltage rating of +6.5V. Its operational input range is specified from 1.4V to 6.0V. Exceeding 6.5V may cause permanent damage. For reliable long-term operation, VIN should remain within the 1.4V–6.0V range, especially under worst-case thermal conditions where power dissipation increases.
Does the MCP1711T-22I/5X require an output capacitor to maintain stability?
No, the MCP1711T-22I/5X is internally compensated for capacitorless operation and remains stable with zero output capacitance. However, adding a low-ESR ceramic capacitor (e.g., 1 µF) improves load transient response and PSRR performance - particularly important in systems with pulsed loads like RF transceivers or sensors.
How does the SHDN pin function on the MCP1711T-22I/5X?
The SHDN pin on the MCP1711T-22I/5X is an active-high enable input. When pulled above 0.91 V (typical), the regulator enables and delivers 2.2V to VOUT. When pulled below 0.38 V (typical), the output shuts down and the internal discharge transistor activates, pulling VOUT to GND through a ~450 Ω path - ensuring rapid, controlled discharge of external capacitors.
What is the dropout voltage of the MCP1711T-22I/5X at 150 mA load?
At 150 mA load and +25°C, the MCP1711T-22I/5X exhibits a typical dropout voltage of 0.92 V (max 1.29 V) - defined as the VIN–VOUT differential at which VOUT drops 2% below nominal. This allows regulation from a 3.12V minimum input, supporting use with partially discharged Li-ion or alkaline cells.
Is the MCP1711T-22I/5X RoHS compliant and lead-free?
Yes, the MCP1711T-22I/5X is EU RoHS compliant and lead-free, as confirmed in the official Microchip datasheet DS20005415D. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly and is compatible with standard reflow profiles.
