Product details
Overview
TC1107-5.0VUA from Microchip Technology is a fixed-output 5.0V 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-optimized for battery-powered medical instruments and portable computing systems.
For engineers reviewing the TC1107-5.0VUA datasheet, TC1107-5.0VUA pinout, TC1107-5.0VUA application, or TC1107-5.0VUA equivalent, key selection criteria include ultra-low noise operation (260nV/√Hz), shutdown mode reducing supply current to 0.05μA, Bypass input for reference filtering, and thermal/overcurrent protection-critical for space-constrained, low-power embedded designs.
Technical Context
The TC1107-5.0VUA implements a CMOS-based regulation architecture that maintains stable 5.0V output across 0–300mA load range without increasing supply current with load-a key upgrade over legacy bipolar LDOs. Its internal reference is decoupled via a dedicated Bypass pin, enabling optional 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 junction temperature, with automatic recovery at ~140°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±0.5% (±25mV) at 25°C, ensuring precision biasing for analog sensors and microcontroller I/O rails. |
| Max Output Current | 300mA continuous-supports moderate-power peripherals like LCD drivers or RF front-end ICs without external pass transistors. |
| Dropout Voltage | 270mV max at 300mA load-enables operation from 5.27V input, critical for single-cell Li-ion or regulated SMPS post-regulation. |
| Quiescent Current | 50μA typ at full load-20–60× lower than bipolar LDOs, extending battery life in always-on monitoring circuits. |
| PSRR | 60dB at ≤1kHz-effectively suppresses low-frequency switching noise from upstream DC/DC converters. |
| Output Noise | 260nV/√Hz at 1kHz-ultra-low noise achieved via internal reference bypass, suitable for ADC reference supplies and audio signal chains. |
| Shutdown Current | 0.05μA typ-reduces system standby power to negligible levels, enabling long-term data logging on coin cells. |
Pinout & Package
TC1107-5.0VUA is housed in an 8-pin MSOP package (3.10 × 3.10 × 1.10 mm), optimized for high-density PCB layouts. The package features exposed pad thermal enhancement and standard tape-and-reel packaging (2500 pcs/reel, 13" reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 8) | Unregulated input supply | Accepts 2.7–6.0V; must exceed VOUT + dropout (≥5.27V for 5.0V output at 300mA). |
| VOUT (Pin 3) | Regulated 5.0V output | Delivers up to 300mA; requires ≥1μF ceramic output capacitor for stability. |
| GND (Pin 4) | Ground reference | Common return path for input, output, and internal circuitry; connects to PCB ground plane for thermal dissipation. |
| Bypass (Pin 5) | Reference bypass input | Connects to 470pF capacitor to ground to reduce internal reference noise, lowering output noise by >50%. |
| SHDN (Pin 6) | Active-high shutdown control | Logic high (≥45% VIN) enables regulation; logic low (≤15% VIN) disables output and reduces IQ to 0.05μA. |
| NC (Pins 1, 2, 7) | No-connect terminals | Internally unconnected; must remain floating or tied to GND per layout best practices-no functional role. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise operation | 260nV/√Hz output noise with optional 470pF Bypass capacitor-enables clean power for precision analog front-ends. |
| CMOS process architecture | Supply current remains constant across 0–300mA load-eliminates load-dependent IQ drift seen in bipolar regulators. |
| Thermal and overcurrent protection | Automatic shutdown at 150°C junction temp and current limiting at ~600mA-prevents damage during fault conditions. |
| Stable with minimal output capacitance | Guaranteed stability with only 1μF ceramic output capacitor-reduces BOM count and board area vs. traditional LDOs requiring ≥10μF. |
| Wide input voltage range | Operates from 2.7V to 6.0V-supports direct connection to Li-ion batteries (2.7–4.2V) and 5V SMPS outputs. |

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 output, but SOT-23-5 package; 2.3μA IQ (lower), 250mA max output (lower), no Bypass pin. | Lacks reference bypass capability-unsuitable where ultra-low noise is required. | Prefer TC1107-5.0VUA when noise-sensitive analog rails demand Bypass functionality and 300mA drive. |
| TPS76350DBVR | 5.0V fixed output, 150mA max, 85μA IQ, SO-8 package; includes enable pin but no Bypass input. | Lower current rating and higher IQ limit use in high-load or ultra-low-power scenarios. | Choose TC1107-5.0VUA for higher output current, lower quiescent current, and noise-suppression capability. |

FAQ
What is the minimum input voltage required for TC1107-5.0VUA to regulate 5.0V at 300mA?
The TC1107-5.0VUA requires a minimum input voltage of 5.27V to maintain 5.0V output at 300mA load, based on its maximum dropout voltage of 270mV. This ensures reliable operation from sources such as fully charged Li-ion batteries (4.2V) only when paired with a pre-regulator, or directly from 5.5V SMPS outputs.
Does TC1107-5.0VUA require an external capacitor on the Bypass pin?
No, the Bypass pin on TC1107-5.0VUA is optional: connecting a 470pF capacitor to ground reduces output noise significantly (e.g., from 260nV/√Hz to <100nV/√Hz), but leaving it unconnected still yields full regulation. Use only if ultra-low noise is critical for ADC references or RF biasing.
Can TC1107-5.0VUA be used with ceramic output capacitors?
Yes, TC1107-5.0VUA is stable with ≥1μF ceramic output capacitors having ESR between 0.1Ω and 5.0Ω-confirmed in the datasheet. This eliminates need for bulkier tantalum or aluminum electrolytic types, saving board space and improving reliability in wide-temperature applications.
What happens to the output voltage of TC1107-5.0VUA during shutdown?
When the SHDN pin is driven low (≤15% VIN), TC1107-5.0VUA enters shutdown mode: VOUT falls to 0V, and supply current drops to 0.05μA (typical). This provides true output disable-critical for isolating downstream circuitry and minimizing system standby power.
Is TC1107-5.0VUA compatible with lead-free reflow soldering processes?
Yes, TC1107-5.0VUA in MSOP package is rated for standard lead-free reflow profiles (JEDEC J-STD-020), with peak temperature tolerance up to 260°C. Its package construction and die attach materials meet RoHS and REACH compliance requirements for modern electronics assembly.
