Product details
Overview
TC1107-2.7VOA from Microchip Technology is a fixed-output, 2.7V CMOS low-dropout (LDO) voltage regulator with ±0.5% output accuracy, 300mA output current capability, 240mV typical dropout at full load, and 50μA typical quiescent current. It integrates shutdown control, bypass input for ultra-low-noise operation, and over-temperature/over-current protection-designed for battery-powered medical instruments and portable communication devices.
For engineers reviewing the TC1107-2.7VOA datasheet, TC1107-2.7VOA pinout, TC1107-2.7VOA application, or TC1107-2.7VOA equivalent, key selection criteria include its 2.7V fixed output, MSOP-8 package compatibility, 0.05μA shutdown current, 260nV/√Hz output noise performance, and stability with only 1μF output capacitance.
Technical Context
The TC1107-2.7VOA employs a CMOS-based regulation architecture that maintains constant 50μA supply current across 0–300mA load range-unlike bipolar LDOs whose quiescent current rises with load. 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 line regulation of 0.05% typical and load regulation of 1.1% typical. Thermal shutdown activates at 150°C junction temperature, and the device remains stable with ceramic, tantalum, or aluminum electrolytic output capacitors ≥1μF and ESR between 0.1Ω and 5.0Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±0.5% - ensures precise biasing for 2.7V logic rails and analog sensors without external feedback. |
| Max Output Current | 300mA - supports moderate-power microcontrollers, RF front-ends, or sensor signal chains in portable systems. |
| Dropout Voltage | 270mV max at 300mA - enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.2V min) with margin. |
| Quiescent Current | 50μA typical at full load - extends battery life in always-on monitoring applications by 20–60× vs. legacy bipolar regulators. |
| Shutdown Current | 0.05μA typical - reduces system standby power to nanoampere level when host MCU asserts SHDN low. |
| Output Noise | 260nV/√Hz at 1kHz - meets low-noise requirements for ADC references, precision amplifiers, and RF synthesizers. |
| PSRR | 60dB at ≤1kHz - suppresses ripple from switching power supply stages used upstream in hybrid SMPS/LDO architectures. |
Pinout & Package
TC1107-2.7VOA is housed in an 8-pin MSOP package (3.0mm × 3.0mm × 1.1mm height), with exposed pad not electrically connected. Pin 1 is marked by a beveled corner; thermal resistance θJA = 200°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VOUT | Regulated output | Delivers stable 2.7V to load; requires ≥1μF ceramic/tantalum capacitor to GND for stability. |
| 2: GND | Ground reference | Primary return path for load and internal circuitry; must connect to low-impedance system ground plane. |
| 3: NC | No connect | Internally unconnected; leave floating or tie to GND per layout best practice-no functional impact. |
| 4: Bypass | Reference bypass input | Accepts 470pF capacitor to GND to reduce internal reference noise and lower output noise by >50%. |
| 5: SHDN | Active-high shutdown control | Logic high (≥45% VIN) enables regulator; logic low (≤15% VIN) disables output and cuts supply current to 0.05μA. |
| 6: NC | No connect | Internally unconnected; no routing or connection required. |
| 7: NC | No connect | Internally unconnected; no routing or connection required. |
| 8: VIN | Unregulated input | Accepts 2.7–6.0V input; requires local 1μF decoupling if >10" wire length or battery source present. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50μA typical across full 0–300mA load range-enables multi-year battery life in IoT endpoint sensors. |
| Bypass-enabled noise reduction | 260nV/√Hz output noise with 470pF on Bypass pin-supports 12-bit+ ADCs and low-phase-noise VCOs. |
| Fast transient response | Maintains regulation during 100mA step-load changes without external compensation-ideal for burst-mode processors. |
| Integrated protection | Auto-recovering thermal shutdown (150°C trip) and foldback current limiting-eliminates need for external fault management. |
| Minimal external components | Stable with only 1μF output capacitor and optional 470pF bypass-reduces BOM count and PCB area vs. legacy LDOs. |
Applications
| Portable Medical Sensors | GSM/PHS Handset Power Rails |
|---|---|
Use Scenario: Continuous glucose monitor with Bluetooth LE radio and ultra-low-power MCU. IC Role / Device Role / Timing Role: Primary 2.7V LDO supplying analog front-end, ADC reference, and BLE SoC I/O domain. Use Value: 50μA quiescent current extends coin-cell lifetime beyond 2 years; 260nV/√Hz noise ensures <1 LSB ADC error. |
Use Scenario: Dual-voltage GSM transceiver requiring clean 2.7V for RF synthesizer and baseband logic. IC Role / Device Role / Timing Role: Post-regulator after buck converter, filtering switcher ripple before sensitive RF sections. Use Value: 60dB PSRR at 1kHz attenuates 100mVpp SMPS ripple to <0.1mVpp, preventing LO phase noise degradation. |
| Linear Post-Regulator for SMPS | Battery-Backed RTC & SRAM |
Use Scenario: Industrial PLC with 5V buck converter feeding 2.7V rail for isolated CAN transceivers and analog I/O. IC Role / Device Role / Timing Role: Low-noise linear post-regulator eliminating SMPS-induced EMI in measurement circuits. Use Value: 240mV typical dropout allows operation down to 2.94V input-maximizing usable battery voltage range. |
Use Scenario: Automotive body controller retaining real-time clock and 64KB SRAM during ignition-off battery drain. IC Role / Device Role / Timing Role: Always-on 2.7V regulator enabling zero-power retention mode with 0.05μA shutdown current. Use Value: Shutdown current <0.1μA prevents measurable battery depletion over 10-year vehicle service life. |
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, 250mA rating, but SOT-23-5 package; 1.6μA quiescent current (higher than TC1107-2.7VOA's 50μA). | Lacks Bypass pin and shutdown control-unsuitable for noise-critical or power-gated designs. | Choose MCP1700 only when board space is constrained and ultra-low IQ or noise suppression is not required. |
| TPS76327QDBVRQ1 | Automotive-grade 2.7V LDO, 150mA, 85μA IQ, integrated thermal/overcurrent protection, but no Bypass pin. | Qualified to AEC-Q100 Grade 3 (−40°C to 125°C), whereas TC1107-2.7VOA is industrial grade (−40°C to 125°C). | Choose TPS76327QDBVRQ1 only for automotive under-hood applications requiring AEC-Q100 qualification. |
Compared with MCP1700-2702E/TO and TPS76327QDBVRQ1, TC1107-2.7VOA uniquely combines 300mA output, 50μA IQ, Bypass-enabled ultra-low noise, and active shutdown in an MSOP-8 package-making it optimal for portable, battery-sensitive, and noise-critical industrial designs where those features are mandatory.

FAQ
What is the minimum input voltage required for TC1107-2.7VOA to regulate at full 300mA load?
The TC1107-2.7VOA requires VIN ≥ 2.7V + dropout voltage. At 300mA, max dropout is 270mV, so minimum VIN is 2.97V. Per datasheet Note 7, VIN must also be ≥2.7V regardless of load-thus 2.97V is the practical minimum for full-load regulation. Below this, output voltage drops out of specification.
Can TC1107-2.7VOA operate with a 1μF ceramic output capacitor?
Yes, TC1107-2.7VOA is explicitly characterized and guaranteed stable with a 1μF ceramic output capacitor (ESR 0.1–5.0Ω). Section 3.1 confirms this value is the minimum required; larger values improve transient response but are not necessary for stability.
Does TC1107-2.7VOA require the Bypass pin to be used?
No-Bypass is optional. Leaving it open achieves standard 260nV/√Hz noise. Connecting a 470pF capacitor reduces noise further; larger values increase startup time but do not harm functionality. The pin has no effect on regulation if unused.
What happens to VOUT when SHDN is pulled low on TC1107-2.7VOA?
When SHDN is driven below 15% VIN (VIL), TC1107-2.7VOA enters shutdown: VOUT falls to 0V, and supply current drops to 0.05μA typical. Output is fully disabled-not high-impedance-so no external discharge path is needed for rapid VOUT decay.
Is TC1107-2.7VOA compatible with tantalum output capacitors?
Yes. Datasheet Section 3.1 explicitly permits solid tantalum capacitors for TC1107-2.7VOA, especially recommended for operation below −25°C where aluminum electrolytics freeze. Minimum 1μF value and ESR limits (0.1–5.0Ω) apply equally to tantalum types.
