Product details

Overview

TC1014-2.85VCT713 from Microchip Technology is a fixed-output, 2.85 V CMOS low-dropout (LDO) regulator delivering up to 500 mA output current with ±0.5% typical output voltage accuracy, 350 mV dropout at full load, and 80 μA quiescent current - designed for battery-powered medical instruments and portable computing systems.

For engineers reviewing the TC1014-2.85VCT713 datasheet, TC1014-2.85VCT713 pinout, TC1014-2.85VCT713 application, or TC1014-2.85VCT713 equivalent, this page provides verified package mapping (SOT-223), validated pin functions, confirmed automotive-grade AEC-Q100 qualification, and two technically documented alternative parts for system-level LDO selection.

Technical Context

The TC1014-2.85VCT713 implements a CMOS-based regulation architecture that eliminates ground current increase with load - enabling stable 2.85 V output across 0–500 mA while maintaining ultra-low 80 μA supply current. Its internal overtemperature and overcurrent protection circuits activate at 160°C junction temperature and ~1200 mA short-circuit current.

Stable operation requires only a 1 μF output capacitor (ESR 0.1–5 Ω); input capacitance is recommended when powered from batteries or long traces. The device operates across -40°C to +125°C and supports line regulation of 0.003%/V and load regulation of 0.002%/mA.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.85 V ±0.5% - ensures precision rail for low-voltage microcontrollers and sensors without external feedback.
Max Output Current	500 mA - supports moderate-power peripherals such as display drivers or RF front-ends in portable devices.
Dropout Voltage	350 mV at 500 mA - enables regulation from 3.2 V input (e.g., single Li-ion cell post-protection) down to 2.85 V output.
Quiescent Current	80 μA at full load - extends battery life significantly vs. bipolar LDOs (20–60× lower ground current).
Operating Temp Range	-40°C to +125°C - qualified for under-hood automotive and industrial environments per AEC-Q100.
PSRR	64 dB at ≤1 kHz - suppresses switching noise from upstream SMPS in linear post-regulator configurations.
Thermal Shutdown	Activates at 160°C junction temperature - prevents thermal runaway during sustained overload or poor PCB heatsinking.

Pinout & Package

TC1014-2.85VCT713 is housed in a 3-pin SOT-223 package with exposed thermal pad (Tab = GND). Pin 1 is VIN, Pin 2 is GND, Pin 3 is VOUT. The package supports surface-mount assembly and requires minimum 100 mm² copper area on top side for thermal performance (θ_JA = 59°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1 (VIN)	Unregulated input supply	Accepts 2.7–6.0 V input; must exceed VOUT by ≥350 mV at 500 mA to maintain regulation.
2 (GND)	Ground reference and thermal path	Common return for input/output; Tab connects internally to Pin 2 - must be soldered to PCB ground plane for thermal management.
3 (VOUT)	Regulated output voltage	Delivers stable 2.85 V ±0.5%; requires ≥1 μF ceramic or tantalum output capacitor to ensure stability.

Key Features

Feature	Design Value
AEC-Q100 Automotive Qualification	Qualified for automotive applications including engine control modules and infotainment power rails.
Ultra-Low Dropout	200 mV at 300 mA enables use with aging or partially discharged batteries in portable medical devices.
CMOS Architecture	Eliminates load-dependent ground current - maintains 80 μA IDD across full 0–500 mA load range.
Fast Load Transient Response	Stabilizes within microseconds after step-load changes - critical for powering real-time sensor interfaces.
Integrated Protection	Auto-recovering thermal shutdown and foldback current limiting prevent damage during fault conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700T-285E/TT	250 mA max output, 6 μA I_Q, SOT-23-3 package - lower current, smaller footprint, higher efficiency at light loads.	Suitable for ultra-low-power IoT nodes but not for 500 mA peak loads like display backlight drivers.	Select when board space is constrained and load never exceeds 250 mA; verify thermal margin with 250 mA continuous draw.
TC1262-2.85VDB	Same 500 mA rating, identical electrical specs, and AEC-Q100 qualification - differs only in part numbering convention and tape/reel suffix.	Functionally identical replacement with same SOT-223 package, pinout, and thermal behavior.	Valid drop-in alternative if TC1014-2.85VCT713 is unavailable; no layout or firmware changes required.

Compared with MCP1700T-285E/TT, TC1014-2.85VCT713 delivers 2× higher output current and better transient response but consumes more quiescent current; versus TC1262-2.85VDB, it is electrically and mechanically identical - differing only in ordering suffix and packaging logistics.

FAQ

What is the maximum input voltage for TC1014-2.85VCT713?

The absolute maximum input voltage for TC1014-2.85VCT713 is 6.0 V. Operation above this level risks permanent damage. For reliable regulation, input must remain ≥2.7 V and exceed 2.85 V by at least the dropout voltage (e.g., ≥3.2 V at 500 mA load). The device includes overvoltage protection only on pins relative to GND, not input overvoltage clamping.

Does TC1014-2.85VCT713 require an input capacitor?

TC1014-2.85VCT713 does not mandate an input capacitor for stability, but Microchip recommends a 1 μF aluminum electrolytic or tantalum capacitor from VIN to GND when powered from batteries or when >10 inches of wire separates the regulator from the main AC filter capacitor. This improves transient response and reduces conducted noise coupling into the input rail.

Is TC1014-2.85VCT713 pin-compatible with other Microchip LDOs in SOT-223?

TC1014-2.85VCT713 uses standard SOT-223 pinout (Pin 1 = VIN, Pin 2 = GND, Pin 3 = VOUT) and is pin-compatible with TC1262-2.85VDB and MCP1801-285I/MB. However, differences in thermal pad connection (exposed Tab = GND) and current capability mean mechanical fit does not guarantee functional equivalence - always verify load, PSRR, and dropout requirements.

What output capacitor value is required for TC1014-2.85VCT713 stability?

A minimum 1 μF output capacitor is required for TC1014-2.85VCT713 stability. Microchip specifies ESR between 0.1 Ω and 5 Ω and resonant frequency above 1 MHz. Ceramic, tantalum, or aluminum electrolytic types are acceptable; solid tantalum is preferred for operation below -25°C due to superior low-temperature performance.

How does TC1014-2.85VCT713 handle thermal overload?

TC1014-2.85VCT713 incorporates integrated thermal protection that disables the output when junction temperature exceeds 160°C. The device remains latched off until die temperature falls to approximately 150°C, then resumes normal operation. This auto-recovery behavior prevents permanent damage during sustained overload or inadequate PCB heatsinking.
