Product details
Overview
TC1107-2.7VUATR from Microchip Technology is a fixed-output, 2.7V CMOS low-dropout (LDO) voltage regulator with shutdown control, delivering up to 300mA output current, ±0.5% output voltage accuracy, and ultra-low 50μA typical supply current. It features a 240mV typical dropout at full load and integrated over-temperature and over-current protection, designed for battery-powered medical instruments and portable communication devices.
For engineers reviewing the TC1107-2.7VUATR datasheet, TC1107-2.7VUATR pinout, TC1107-2.7VUATR application, or TC1107-2.7VUATR equivalent, key selection criteria include its 2.7V fixed output, MSOP-8 package, 0.05μA shutdown current, 470pF bypass input for noise reduction, and stability with only 1μF output capacitance.
Technical Context
The TC1107-2.7VUATR uses a CMOS pass element to achieve 50μA typical quiescent current independent of load - unlike bipolar LDOs - enabling long battery life in always-on systems. Its reference bypass input accepts a 470pF capacitor to reduce internal reference noise, directly lowering output noise to 260nV/√Hz at 1kHz.
Dropout voltage is specified at 270mV max at 300mA load, with thermal shutdown activating at 150°C and automatic recovery at ~140°C. The device maintains regulation across –40°C to +125°C junction temperature and requires no minimum load, supporting RTC and CMOS RAM backup applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±0.5% (±13.5mV), ensuring stable power for precision analog or low-voltage logic rails. |
| Max Output Current | 300mA, sufficient to power microcontrollers, sensors, or RF front-ends in portable designs. |
| Dropout Voltage | 270mV max at 300mA, enabling operation from 2.97V input - critical for single-cell Li-ion or alkaline battery systems. |
| Supply Current | 50μA typical at full load, reducing standby power by 20–60× versus legacy bipolar regulators. |
| Shutdown Current | 0.05μA typical, allowing multi-year battery life in sleep-mode applications like pagers or medical monitors. |
| PSRR | 60dB at ≤1kHz, suppressing ripple from upstream switching regulators in hybrid SMPS/LDO architectures. |
| Output Noise | 260nV/√Hz at 1kHz, minimized further via optional 470pF bypass capacitor on reference node. |
Pinout & Package
TC1107-2.7VUATR is housed in an 8-pin MSOP package (3.0mm × 3.0mm × 1.1mm body height), optimized for space-constrained portable PCBs. Thermal resistance θJA is 200°C/W, requiring minimal copper area for thermal management in ambient temperatures up to +55°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Unregulated input supply | Accepts 2.7V to 6.0V; must exceed VOUT + dropout to maintain regulation. |
| NC (Pin 2) | No-connect terminal | Internally unused; must be left floating or tied to GND per layout best practice. |
| SHDN (Pin 3) | Active-high shutdown control | Logic high (>45% VIN) enables regulator; logic low (<15% VIN) disables output and reduces ISS to 0.05μA. |
| VOUT (Pin 4) | Regulated output | Delivers stable 2.7V ±0.5%; requires ≥1μF ceramic or tantalum output capacitor for stability. |
| GND (Pin 5) | Power ground reference | Common return path for input, output, and internal circuitry; must connect to low-impedance system ground plane. |
| NC (Pin 6) | No-connect terminal | Internally unused; no electrical function; avoid routing signals nearby. |
| Bypass (Pin 7) | Reference bypass input | Connect 470pF capacitor to GND to reduce reference noise and lower output noise by >50%. |
| NC (Pin 8) | No-connect terminal | Internally unused; leave unconnected; do not tie to any voltage rail. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50μA typical at full 300mA load - enables >10-year battery life in low-duty-cycle IoT sensors. |
| Low-noise architecture with bypass | 260nV/√Hz output noise reduced further via 470pF capacitor on Bypass pin - suitable for ADC reference supplies. |
| Fast transient response | Maintains regulation during rapid load steps (e.g., GSM transmit bursts) without external compensation. |
| Thermal & current limiting | Auto-recovering thermal shutdown at 150°C and foldback current limit protect against sustained overload or PCB overheating. |
| Minimal external components | Stable with only 1μF output capacitor - eliminates need for large electrolytics and saves board space. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2702E/TO | Same 2.7V output, SOT-23-5 package, 250mA max output, 1.6μA quiescent current - higher IQ but smaller footprint. | Limited to 250mA; lacks Bypass pin and thermal shutdown; suited for ultra-low-IQ sub-100mA applications. | Select MCP1700-2702E/TO only if board space is constrained and load current remains ≤250mA with no thermal stress risk. |
| TCS2107-2.7VUA | Pin-compatible MSOP-8 upgrade with 300mA rating, 40μA IQ, and improved PSRR (70dB @1kHz); same pinout and Bypass functionality. | Direct functional replacement with enhanced noise rejection and lower quiescent current; identical thermal and protection behavior. | Prefer TCS2107-2.7VUA for new designs requiring higher PSRR and lower IQ without layout changes. |
Compared with TC1107-2.7VUATR, MCP1700-2702E/TO trades output current and protection for ultra-low IQ and smaller size, while TCS2107-2.7VUA offers a drop-in performance upgrade with better PSRR and lower supply current - both require validation of thermal margin and bypass capacitor placement.

FAQ
What is the minimum input voltage required for TC1107-2.7VUATR to regulate properly?
The TC1107-2.7VUATR requires VIN ≥ 2.7V and VIN ≥ VOUT + dropout voltage. With a maximum dropout of 270mV at 300mA, the minimum valid input is 2.97V under full load. At light loads (0.1mA), dropout drops to 20mV, permitting operation down to 2.72V - verified per DS21356C Electrical Characteristics table.
Does TC1107-2.7VUATR require an external bypass capacitor for stable operation?
No - the TC1107-2.7VUATR is stable with only a 1μF output capacitor and does not require the 470pF bypass capacitor for basic regulation. That capacitor is optional and used solely to reduce output noise by filtering the internal reference; omitting it has no effect on stability or regulation accuracy.
Can TC1107-2.7VUATR be used in automotive applications?
The TC1107-2.7VUATR is rated for –40°C to +125°C junction temperature and includes over-temperature and over-current protection, but it is not AEC-Q100 qualified. It may be used in non-safety-critical automotive cabin modules (e.g., infotainment peripherals) with proper derating and system-level validation - not for engine bay or ADAS functions.
What is the purpose of the NC pins on TC1107-2.7VUATR?
TC1107-2.7VUATR has four NC (no-connect) pins - Pins 2, 6, 7, and 8 in MSOP-8 configuration - all internally unconnected. They must remain unconnected in the schematic and layout; tying them to GND or other nets risks parasitic coupling or mechanical stress on bond wires. Pin 7 is Bypass, not NC - confirmed in DS21356C Table 2-1.
How does TC1107-2.7VUATR behave during shutdown mode?
When SHDN is pulled low (<15% VIN), TC1107-2.7VUATR disables its pass element, driving VOUT to 0V and reducing supply current to 0.05μA typical. The device retains full over-temperature and over-current protection in shutdown, and resumes regulation within microseconds upon SHDN rising above 45% VIN - validated in DS21356C Section 3.0.
