Product details
Overview
TC1107-3.0VOATR from Microchip Technology is a fixed-output, 3.0V CMOS low-dropout (LDO) linear regulator with ±0.5% output voltage accuracy, 300mA maximum output current, and ultra-low 50μA typical supply current. It features shutdown control, bypass input for noise reduction, and integrated over-temperature and over-current protection-designed for battery-powered medical instruments and portable computing systems.
For engineers reviewing the TC1107-3.0VOATR datasheet, TC1107-3.0VOATR pinout, TC1107-3.0VOATR application, or TC1107-3.0VOATR equivalent, key selection criteria include dropout voltage at full load (≤480mV), thermal shutdown threshold (150°C), PSRR of 60dB at ≤1kHz, and compatibility with 1μF minimum ceramic output capacitance.
Technical Context
The TC1107-3.0VOATR uses a CMOS pass element to achieve stable regulation across 0–300mA load range without supply current increase-unlike legacy bipolar LDOs. Its reference bypass input accepts a 470pF capacitor to reduce internal reference noise, directly lowering output noise to 260nV/√Hz at 1kHz.
Shutdown logic is CMOS-compatible: SHDN ≥45% VIN enables regulation; SHDN ≤15% VIN disables output and reduces supply current to 0.05μA. Thermal protection activates at 150°C junction temperature and releases at ~140°C, ensuring safe operation under sustained overload or high ambient conditions.
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 microcontrollers. |
| Max Output Current | 300mA continuous; supports power rails for ARM Cortex-M peripherals, sensor hubs, and RF front-end ICs. |
| Dropout Voltage | 270mV max at 300mA load; enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.0V nominal) sources. |
| Supply Current | 50μA typical at full load; 20–60× lower than bipolar LDOs, extending battery life in always-on monitoring devices. |
| PSRR | 60dB at ≤1kHz; suppresses ripple from upstream switching regulators in hybrid SMPS/LDO power architectures. |
| Output Noise | 260nV/√Hz at 1kHz (1μF COUT, 50Ω load); meets low-noise requirements for analog signal chains and precision sensors. |
| Shutdown Current | 0.05μA typical; enables deep-sleep modes in portable instrumentation with <1μA system standby budgets. |
Pinout & Package
TC1107-3.0VOATR is packaged in an 8-pin MSOP (Mini Small Outline Package) with 0.65mm lead pitch and 3.0mm × 3.0mm body size. The package is RoHS-compliant and optimized for thermal performance (θJA ≈ 200°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Regulated 3.0V output; requires ≥1μF ceramic capacitor to GND for stability and transient response. |
| 2 | GND | Analog/digital ground reference; must be connected to low-impedance PCB ground plane to minimize noise coupling. |
| 3 | NC | No-connect; left unconnected per datasheet-no internal connection or function. |
| 4 | Bypass | Reference bypass node; adding 470pF to GND reduces output noise by filtering internal bandgap reference ripple. |
| 5 | SHDN | Active-high shutdown control; logic high (>45% VIN) enables regulation; logic low (<15% VIN) disables output and cuts supply current to 0.05μA. |
| 6 | NC | No-connect; no internal connection-must remain floating or grounded (not driven). |
| 7 | NC | No-connect; no internal connection-must remain floating or grounded (not driven). |
| 8 | VIN | Unregulated input (2.7–6.0V); must be decoupled with ≥1μF capacitor if sourced from battery or >10-inch wiring. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50μA typical at full 300mA load-enables multi-year battery life in remote medical telemetry nodes. |
| Low-noise operation with bypass | 260nV/√Hz output noise reduced further via 470pF on Bypass pin-critical for ECG front-ends and audio codec supplies. |
| Fast load transient response | Maintains regulation during 100mA step loads with minimal undershoot-supports burst-mode wireless transceivers (e.g., BLE, Zigbee). |
| Thermal and current limiting | Auto-shutdown at 150°C junction temp and current limit ~600mA-prevents damage during short-circuit or PCB layout faults. |
| Stable with small output cap | Guaranteed stability with only 1μF ceramic output capacitor-reduces BOM cost and board area vs. traditional 10μF tantalum solutions. |

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 250mA max current and 1.8μA quiescent current; no shutdown or bypass pin. | Better for ultra-low-power always-on sensors; unsuitable for 300mA loads or noise-sensitive analog rails. | Choose MCP1700-3002E/TO only when load current ≤250mA and shutdown/bypass functionality is unnecessary. |
| TCS2117-3.0 | 300mA output, 65μA quiescent current, no bypass pin, and 400mV dropout at 300mA; same SOIC/MSOP footprint. | Higher dropout and noise limit use in low-input-voltage or precision analog systems. | Select TCS2117-3.0 only when pin compatibility with TC1107-3.0VOATR is required and 400mV dropout is acceptable. |
Compared with MCP1700-3002E/TO and TCS2117-3.0, TC1107-3.0VOATR uniquely delivers 300mA output, 50μA IQ, 270mV dropout, and bypass-enabled ultra-low noise-making it the only option meeting all four requirements simultaneously for high-fidelity portable instrumentation.

FAQ
What is the maximum input voltage rating for TC1107-3.0VOATR?
The absolute maximum input voltage for TC1107-3.0VOATR is 6.5V, but the recommended operating range is 2.7V to 6.0V. Exceeding 6.5V risks permanent damage. For reliable operation with a 3.0V output, VIN must be ≥3.27V to maintain regulation at full 300mA load due to dropout constraints.
Does TC1107-3.0VOATR require an external bypass capacitor for basic operation?
No, TC1107-3.0VOATR operates stably without the bypass capacitor. The 470pF capacitor on the Bypass pin is optional and used solely to reduce output noise-typically applied in precision analog or RF-sensitive designs. Leaving Bypass unconnected maintains full regulation and safety margins.
Can TC1107-3.0VOATR be used with ceramic output capacitors?
Yes, TC1107-3.0VOATR is explicitly designed for stability with ≥1μF ceramic output capacitors (ESR 0.1–5.0Ω). This eliminates need for larger, less reliable tantalum or aluminum electrolytic capacitors-reducing cost, size, and failure risk in space-constrained portable designs.
What happens to the output voltage of TC1107-3.0VOATR during shutdown?
When the SHDN pin is pulled low (<15% VIN), TC1107-3.0VOATR disables its pass element, causing VOUT to fall to 0V. Simultaneously, supply current drops to 0.05μA typical. This behavior ensures complete power isolation for downstream circuits during sleep or fault conditions.
Is TC1107-3.0VOATR compatible with lead-free reflow soldering processes?
Yes, TC1107-3.0VOATR in MSOP packaging is rated for standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260°C. The device meets RoHS Directive 2011/65/EU and is manufactured with halogen-free molding compound.
