Product details
Overview
TC1017-2.7VLTTR from Microchip Technology is a fixed-output, 2.7 V CMOS low-dropout (LDO) linear voltage regulator in SC-70 package, delivering up to 150 mA output current with 285 mV typical dropout at full load, ±0.5% output voltage accuracy, and 53 µA typical quiescent current - optimized for battery-powered portable electronics including medical instruments and cellular handsets.
For engineers reviewing the TC1017-2.7VLTTR datasheet, TC1017-2.7VLTTR pinout, TC1017-2.7VLTTR application, or TC1017-2.7VLTTR equivalent, key selection criteria include shutdown current (0.05 µA typ), wake-up time (10 µs typ), ceramic capacitor compatibility (1 µF min), thermal shutdown (160°C), and SC-70 footprint reduction versus SOT-23.
Technical Context
The TC1017-2.7VLTTR uses a P-channel MOSFET pass element with internal bandgap reference and error amplifier feedback, enabling stable regulation across 2.7–6.0 V input and 0–150 mA load without external resistors. Its body diode (cathode at VIN, anode at VOUT) supports reverse-voltage protection in battery systems.
It integrates overcurrent limiting (120 mA typ during short-circuit), thermal shutdown with 10°C hysteresis, and fast transient response - achieving 32 µs typical settling time from shutdown with 1 µF ceramic output capacitance. Input and output stability are guaranteed with 0–2 Ω ESR capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±0.5% (typ), ensuring precision biasing for 2.7 V logic or analog circuitry without trimming. |
| Max Output Current | 150 mA at VIN ≥ 3.0 V and VIN ≥ (2.7 V + 2.5%) + VDROPOUT, supporting moderate-power microcontrollers and sensors. |
| Dropout Voltage | 285 mV (typ) at 150 mA load, enabling operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.2 V min). |
| Quiescent Current | 53 µA (typ) across full 0–150 mA load range, extending battery life in always-on portable devices. |
| Shutdown Current | 0.05 µA (typ), reducing standby power loss in sleep-mode systems such as pagers and medical monitors. |
| Wake-Up Time | 10 µs (typ) from SHDN assertion, enabling rapid system responsiveness in duty-cycled applications. |
| Input Voltage Range | 2.7 V to 6.0 V, compatible with wide-input battery sources and post-regulation supplies. |
Pinout & Package
TC1017-2.7VLTTR is supplied in a 5-pin SC-70 package (JEDEC MO-203AA), offering 50% smaller footprint than SOT-23 and optimized for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SHDN | Active-low shutdown control: logic high (>45% VIN) enables regulation; logic low (<15% VIN) disables output and reduces IIN to 0.05 µA. |
| 2 | NC | No-connect terminal - must remain unconnected per design; no internal connection or function. |
| 3 | GND | Ground reference for regulator feedback and error amplifier; requires low-impedance connection to PCB ground plane. |
| 4 | VOUT | Stable 2.7 V regulated output; requires ≥1 µF ceramic capacitor (X5R/X7R, ESR ≤2 Ω) placed adjacent to pin for stability. |
| 5 | VIN | Unregulated input supply (2.7–6.0 V); requires local 0.1–1 µF ceramic bypass capacitor near pin to suppress source impedance effects. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS P-channel architecture | Eliminates need for external pull-up on SHDN and avoids N-channel gate-drive complexity in low-VIN systems. |
| 1 µF ceramic output capacitor support | Reduces BOM cost and board area vs. traditional LDOs requiring ≥10 µF tantalum or electrolytic capacitors. |
| ±0.5% output voltage accuracy (typ) | Meets tight tolerance requirements for ADC references, RF bias rails, and low-voltage microcontroller cores. |
| Thermal shutdown with hysteresis | Auto-recovers from overload without manual reset; 160°C trip / 150°C release prevents latch-up during intermittent faults. |
| Low-noise operation (800 nV/√Hz @ 10 kHz) | Minimizes supply-induced jitter in sensitive analog circuits like audio codecs or sensor front-ends. |

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 2.7 V output, but SOT-23-5 package; higher 250°C/W θJA; 1.8 µA quiescent current (lower IQ but lower max IOUT = 250 mA). | Preferred where board layout accommodates SOT-23 and ultra-low IQ dominates over footprint size. | Select MCP1700-2702E/TO if thermal budget permits larger package and sub-µA shutdown is critical. |
| TPS76327QDBVRQ1 | Automotive-grade (-40°C to +125°C), same 2.7 V output and SC-70 package; 85 µA IQ; 150 mA rated output; AEC-Q100 qualified. | Required for automotive infotainment or telematics modules needing qualification and extended temperature compliance. | Choose TPS76327QDBVRQ1 only when AEC-Q100 qualification and automotive temperature range are mandatory. |
Compared with MCP1700-2702E/TO, TC1017-2.7VLTTR offers superior thermal performance in SC-70 (θJA = 450°C/W vs. 250°C/W for SOT-23) and faster wake-up (10 µs vs. 50 µs), while TPS76327QDBVRQ1 adds automotive qualification at the cost of higher quiescent current and price premium.

FAQ
What is the maximum input voltage rating for TC1017-2.7VLTTR?
The absolute maximum input voltage for TC1017-2.7VLTTR is 6.0 V. Operation above this level risks permanent damage. For reliable regulation, VIN must also satisfy VIN ≥ (2.7 V + 2.5%) + VDROPOUT - typically requiring ≥2.985 V minimum under full load. The device includes internal overvoltage clamp protection on all pins rated to VIN + 0.3 V.
Does TC1017-2.7VLTTR require an external resistor network to set output voltage?
No, TC1017-2.7VLTTR is a fixed-output regulator with internally trimmed 2.7 V reference. The output voltage is set by laser-trimmed feedback resistors inside the die - no external components are needed for voltage programming. This eliminates calibration overhead and improves long-term stability versus adjustable LDOs.
Can TC1017-2.7VLTTR operate with a 1 µF ceramic output capacitor?
Yes, TC1017-2.7VLTTR is explicitly designed and tested for stability with a minimum 1 µF X5R or X7R ceramic capacitor (ESR 0–2 Ω) on VOUT. This is confirmed in the datasheet's Electrical Characteristics table and Figure 4-2 typical application circuit. Larger values improve transient response but are not required.
What is the thermal shutdown behavior of TC1017-2.7VLTTR?
TC1017-2.7VLTTR initiates thermal shutdown at approximately 160°C junction temperature and resumes operation once the die cools to ~150°C, providing 10°C hysteresis. During shutdown, the P-channel MOSFET turns off, dropping VOUT to 0 V and reducing supply current to 0.05 µA. This protects against sustained overloads without requiring external intervention.
Is TC1017-2.7VLTTR pin-compatible with bipolar LDOs?
Yes, TC1017-2.7VLTTR is explicitly designed as a pin-compatible CMOS upgrade for legacy bipolar LDOs in SC-70 and SOT-23 packages. Its SHDN, GND, VOUT, VIN, and NC pin assignments match industry-standard footprints, enabling drop-in replacement without PCB revision - provided thermal and electrical margins are verified per application conditions.
