Product details
Overview
TC1107-5.0VOATR from Microchip Technology is a fixed-output 5.0V 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 over-temperature/over-current protection - designed for battery-powered medical instruments and portable computing systems.
For engineers reviewing the TC1107-5.0VOATR datasheet, TC1107-5.0VOATR pinout, TC1107-5.0VOATR application, or TC1107-5.0VOATR equivalent, key selection criteria include dropout voltage at full load (270mV max), thermal shutdown threshold (150°C), PSRR of 60dB at ≤1kHz, and compatibility with 1µF minimum ceramic output capacitance.
Technical Context
The TC1107-5.0VOATR 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 functionality reduces supply current to 0.05µA (typical) while forcing VOUT to zero; SHDN input thresholds are defined as VIH ≥ 45% VIN and VIL ≤ 15% VIN, enabling direct interfacing with CMOS logic or microcontroller I/O pins without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±0.5% (±25mV) at 25°C; ensures stable power for 5V-tolerant logic and analog circuitry. |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like sensors, RF modules, or display drivers. |
| Dropout Voltage | 270mV max at 300mA load - enables operation from 5.27V input, critical for single-cell Li-ion or regulated SMPS post-regulation. |
| Supply Current | 50µA typical at full load - 20–60× lower than bipolar LDOs, extending battery life in always-on monitoring systems. |
| PSRR | 60dB at ≤1kHz - suppresses ripple from switching regulators upstream, preserving signal integrity in precision analog stages. |
| Output Noise | 260nV/√Hz at 1kHz - minimized via optional 470pF bypass capacitor on reference node, suitable for ADC reference supplies. |
| Thermal Shutdown | Activates at 150°C junction temperature - protects device during sustained overload or poor PCB thermal design. |
Pinout & Package
TC1107-5.0VOATR is supplied in an 8-pin MSOP package (3.0mm × 3.0mm × 0.85mm body, 0.65mm pitch), optimized for space-constrained portable designs. Pin 1 is marked by a beveled corner; the package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Unregulated input supply | Accepts 2.7–6.0V; must exceed VOUT + dropout voltage (≥5.27V for 5.0V output at 300mA). |
| GND (Pin 2) | Power ground reference | Low-impedance return path for load and internal circuits; requires solid PCB ground plane for thermal and noise performance. |
| NC (Pin 3) | No-connect terminal | Internally unconnected; must remain floating - no external connection permitted. |
| Bypass (Pin 4) | Reference bypass input | Connect 470pF capacitor to GND to reduce output noise; left open if ultra-low noise not required. |
| SHDN (Pin 5) | Active-high shutdown control | Logic high (≥45% VIN) enables regulator; logic low (≤15% VIN) disables output and reduces IQ to 0.05µA. |
| NC (Pin 6) | No-connect terminal | Internally unconnected; must remain floating - no external connection permitted. |
| NC (Pin 7) | No-connect terminal | Internally unconnected; must remain floating - no external connection permitted. |
| VOUT (Pin 8) | Regulated 5.0V output | Delivers up to 300mA; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50µA typical at full 300mA load - enables multi-year battery operation in low-duty-cycle IoT endpoints. |
| Fixed 5.0V output with high accuracy | ±0.5% tolerance over -40°C to +125°C - eliminates need for external feedback resistors or trimming in 5V system rails. |
| Integrated protection | Auto-recovering over-temperature shutdown (150°C trip) and current-limiting (550–650mA short-circuit limit) - prevents damage under fault conditions. |
| Low-noise operation | 260nV/√Hz output noise with 470pF bypass capacitor - meets noise requirements for precision ADCs, DACs, and RF bias supplies. |
| Fast load transient response | Maintains regulation during 100mA step changes without external compensation - simplifies design for dynamic loads like microcontroller wake-up events. |
Applications
| Portable Medical Sensors | Battery-Powered Data Loggers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-5002E/TO | Same 5.0V fixed output, but 250mA max current and 1.8µA quiescent current - lower IQ but reduced drive capability. | Suitable for ultra-low-power microcontrollers (e.g., PIC12LF) but insufficient for 300mA loads like LCD backlights. | Select when standby current dominates design priority and peak load stays below 250mA. |
| NCP1117ST50T3G | Bipolar-based 5.0V LDO with 1A rating, but 6mA quiescent current and 1.2V dropout - higher power loss and noise. | Used where high current and ruggedness outweigh efficiency and noise concerns, e.g., industrial PLC I/O modules. | Choose only if 300mA+ current and wide-input tolerance (up to 20V) are mandatory and thermal/noise budgets allow. |
Compared with MCP1700-5002E/TO, TC1107-5.0VOATR delivers 20% higher output current with 27× higher quiescent current - favoring active-load scenarios. Against NCP1117ST50T3G, it trades 70% lower IQ and 55% lower dropout for 70% less max current - optimizing for battery runtime and thermal headroom in compact devices.

FAQ
What is the minimum input voltage required for TC1107-5.0VOATR to regulate 5.0V at 300mA?
The TC1107-5.0VOATR requires a minimum input voltage of 5.27V to maintain regulation at 300mA load, based on its maximum dropout voltage of 270mV. This value satisfies both the dropout condition (VIN ≥ VOUT + VDROPOUT) and the absolute minimum VIN specification of 2.7V stated in the datasheet.
Can TC1107-5.0VOATR operate without the bypass capacitor on the Bypass pin?
Yes, TC1107-5.0VOATR operates fully functional without the 470pF bypass capacitor on the Bypass pin. The capacitor is optional and only required when ultra-low output noise (260nV/√Hz) is needed; omitting it increases noise but does not affect regulation, stability, or basic functionality of the TC1107-5.0VOATR.
What happens to the output voltage of TC1107-5.0VOATR during shutdown?
When the SHDN pin of TC1107-5.0VOATR is pulled low (≤15% VIN), the device enters shutdown mode: the output voltage falls to zero volts, and supply current drops to 0.05µA (typical). This behavior ensures complete power isolation and eliminates leakage into downstream circuitry.
Is TC1107-5.0VOATR stable with ceramic output capacitors?
Yes, TC1107-5.0VOATR is explicitly characterized for stability with a minimum 1µF ceramic output capacitor (ESR > 0.1Ω and < 5.0Ω). Unlike many older LDOs, it does not require tantalum or aluminum electrolytic types - enabling smaller, more reliable, and temperature-stable designs.
Does TC1107-5.0VOATR have built-in reverse polarity protection?
No, TC1107-5.0VOATR does not include reverse polarity protection. Applying reverse voltage to VIN or VOUT may damage the device. External protection - such as a series Schottky diode on VIN or a reverse-biased TVS - must be implemented if reverse input conditions are possible in the end application.
