Product details
Overview
TC1107-3.0VUATR from Microchip Technology is a fixed-output, 3.0V CMOS low-dropout (LDO) linear regulator in an 8-pin MSOP package, delivering up to 300mA output current with ±0.5% output voltage accuracy, 240mV typical dropout at full load, and 50μA typical quiescent current-designed for battery-powered medical instruments and portable communication devices.
For engineers reviewing the TC1107-3.0VUATR datasheet, TC1107-3.0VUATR pinout, TC1107-3.0VUATR application, or TC1107-3.0VUATR equivalent, key selection criteria include ultra-low noise operation (260nV/√Hz), shutdown mode reducing supply current to 0.05μA, bypass-capable reference for enhanced PSRR, and thermal/overcurrent protection-critical for space-constrained, low-power embedded systems.
Technical Context
The TC1107-3.0VUATR uses a CMOS-based regulation architecture that maintains stable output voltage across 0–300mA load range without increasing supply current-a key distinction from legacy bipolar LDOs. Its internal reference is accessible via the Bypass pin, enabling external 470pF capacitor connection to reduce output noise by suppressing reference ripple.
Shutdown control is TTL/CMOS-compatible: SHDN ≥45% VIN enables regulation; ≤15% VIN forces shutdown with VOUT = 0V and ISS2 = 0.05μA (typ). Thermal shutdown activates at 150°C, with automatic recovery at ~140°C, and stability is guaranteed with only 1μF output capacitance (ESR 0.1–5.0Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±0.5% (±15mV) at 25°C; ensures precision biasing for ADC references and low-voltage logic rails. |
| Max Output Current | 300mA continuous-supports moderate-power microcontrollers, sensors, and RF front-end ICs in portable designs. |
| Dropout Voltage | 270mV max at 300mA load-enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.0V fresh) sources. |
| Quiescent Current | 50μA typ at full load-20–60× lower than bipolar LDOs, extending battery life in always-on monitoring applications. |
| PSRR | 60dB at ≤1kHz-effectively suppresses switching noise from upstream SMPS when used as post-regulator. |
| Output Noise | 260nV/√Hz at 1kHz-low-noise performance critical for analog signal chains and precision sensor interfaces. |
| Shutdown Current | 0.05μA typ-reduces system standby power to nanoampere levels, ideal for RTC and memory backup circuits. |
Pinout & Package
TC1107-3.0VUATR is housed in an 8-pin MSOP package (3.0mm × 3.0mm × 1.1mm height), optimized for high-density PCB layouts. Pin 1 is marked by a beveled corner; thermal performance is enhanced by exposed pad grounding (per Microchip packaging spec).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 8) | Unregulated input supply | Accepts 2.7–6.0V; must exceed VOUT + dropout (≥3.27V at 300mA) for regulation; requires local 1μF decoupling if >10" from source. |
| VOUT (Pin 3) | Regulated output | Delivers stable 3.0V ±0.5%; stable with 1μF ceramic or tantalum output capacitor (ESR 0.1–5.0Ω). |
| GND (Pin 2) | Ground reference | Common return path for input, output, and internal circuitry; connect directly to low-impedance ground plane. |
| Bypass (Pin 4) | Reference bypass input | Connects to internal bandgap reference; adding 470pF to GND reduces output noise by filtering reference ripple. |
| SHDN (Pin 5) | Shutdown control input | Active-high logic interface: VIH ≥45% VIN enables regulation; VIL ≤15% VIN disables output and cuts supply current to 0.05μA. |
| NC (Pins 1, 6, 7) | No-connect terminals | Not internally bonded; must remain unconnected per datasheet-no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50μA typical at full 300mA load-minimizes battery drain in always-on portable instrumentation. |
| Low-noise operation with bypass | 260nV/√Hz output noise reduced further via 470pF on Bypass pin-enables clean power for audio codecs and precision ADCs. |
| Fast transient response | Maintains regulation during rapid load steps (e.g., MCU wake-up bursts) without external compensation. |
| Integrated protection | Auto-recovering thermal shutdown (150°C trip) and foldback overcurrent limiting-eliminates need for external fault management. |
| Wide input voltage range | 2.7–6.0V operation supports diverse sources: single Li-ion, dual alkaline, or SMPS pre-regulated rails. |
Applications
| Medical Vital Sign Monitor | Portable GSM Phone Baseband |
|---|---|
Use Scenario: Powering ECG front-end amplifiers and 16-bit SAR ADCs in handheld patient monitors. IC Role / Device Role / Timing Role: Primary 3.0V analog rail regulator with ultra-low noise and high DC accuracy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | Same 3.0V output, but SOT-23-5 package; 2.3μA quiescent current (lower), 250mA max output (lower), no Bypass pin. | Lacks reference bypass capability-unsuitable where <300nV/√Hz noise is required; better for ultra-low-IQ sleep modes. | Select MCP1700-3002E/TO only when board space is more constrained than noise performance, and load ≤250mA. |
| TCS2107-3.0VUA | Pin-compatible MSOP-8 upgrade: same 300mA, ±0.5% accuracy, but adds enable polarity inversion and 1.8V–5.5V input range. | Supports wider input range and inverted EN logic-useful in systems with active-low reset controllers or multi-rail sequencing. | Choose TCS2107-3.0VUA when upgrading legacy TC1107-3.0VUATR designs requiring extended VIN range or inverted shutdown control. |
Compared with MCP1700-3002E/TO and TCS2107-3.0VUA, TC1107-3.0VUATR uniquely balances ultra-low noise (via Bypass), 300mA capability, and proven thermal robustness in MSOP-8-making it optimal for analog-sensitive, medium-current portable systems where reference integrity is non-negotiable.

FAQ
What is the minimum input voltage required for TC1107-3.0VUATR to maintain regulation at 300mA load?
The TC1107-3.0VUATR requires VIN ≥ VOUT + dropout voltage. At 300mA, max dropout is 270mV, so minimum VIN = 3.0V + 0.27V = 3.27V. Additionally, the datasheet specifies VIN ≥ 2.7V as absolute minimum, making 3.27V the functional lower limit under full load. Below this, output voltage drops out of regulation.
Can TC1107-3.0VUATR operate without connecting the Bypass pin?
Yes, TC1107-3.0VUATR operates fully functional with Bypass (Pin 4) left unconnected. The 470pF capacitor is optional and only required when ultra-low output noise (e.g., <300nV/√Hz) is needed for sensitive analog circuits. Leaving it open increases noise to 260nV/√Hz (typ), which remains acceptable for most digital loads.
Does TC1107-3.0VUATR require an external capacitor on the SHDN pin for stable operation?
No, TC1107-3.0VUATR does not require an external capacitor on the SHDN pin. The shutdown input is CMOS-compatible with defined VIH (≥45% VIN) and VIL (≤15% VIN) thresholds. It may be driven directly from a microcontroller GPIO or logic gate; if unused, connect SHDN to VIN to ensure permanent enable-no filtering capacitor is specified or needed.
What is the maximum allowable power dissipation for TC1107-3.0VUATR in the MSOP-8 package?
For the TC1107-3.0VUATR in MSOP-8 (θJA ≈ 200°C/W), maximum allowable power dissipation is calculated as PDMAX = (TJMAX – TAMAX)/θJA. With TJMAX = 125°C and TAMAX = 55°C, PDMAX = (125 – 55)/200 = 350mW. Actual dissipation must stay below this limit-e.g., at VIN = 4.0V, VOUT = 3.0V, IOUT = 300mA: PD ≈ (4.0 – 3.0) × 0.3 = 300mW, within safe margin.
Is TC1107-3.0VUATR compatible with ceramic output capacitors?
Yes, TC1107-3.0VUATR is stable with ceramic output capacitors, provided they meet the 1μF minimum value and ESR specification of 0.1–5.0Ω. Standard X5R/X7R ceramics satisfy this; avoid ultra-low-ESR types (<0.1Ω) unless verified with Microchip's stability guidelines, as they may induce oscillation due to phase margin reduction.
