Product details
Overview
TC1015-2.85VCT713 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% initial accuracy, 350 mV typical dropout at full load, and 80 µA quiescent current. It serves as a precision post-regulator in battery-powered instrumentation and portable medical devices requiring stable low-noise voltage under variable load.
For engineers reviewing the TC1015-2.85VCT713 datasheet, TC1015-2.85VCT713 pinout, TC1015-2.85VCT713 application, or TC1015-2.85VCT713 equivalent, this page delivers verified technical context, package mapping, real-world design meaning for key specs, and two confirmed alternative parts for automotive-grade LDO selection.
Technical Context
The TC1015-2.85VCT713 employs CMOS pass transistor architecture to eliminate ground current increase with load-enabling ultra-low quiescent current (80 µA at full load) and extending battery life in always-on systems. Its internal bandgap reference and error amplifier deliver tight output regulation across temperature (40 ppm/°C drift) and line/load variations.
It integrates overtemperature shutdown (trip at 160°C) and foldback overcurrent protection, remains stable with only 1 µF ceramic output capacitance, and achieves 64 dB PSRR at ≤1 kHz-critical for noise-sensitive analog front-ends in portable diagnostics and sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85 V ±0.5% at 25°C; maintains regulation across -40°C to +125°C junction range. |
| Max Output Current | 500 mA continuous; supports high-current microcontrollers or RF transceivers without thermal derating in SOT-223 with adequate copper. |
| Dropout Voltage | 350 mV typical at 500 mA; enables operation from 3.2 V input when powering 2.85 V logic rails. |
| Quiescent Current | 80 µA at full load; 20–60× lower than bipolar LDOs, preserving battery capacity in standby modes. |
| PSRR | 64 dB at ≤1 kHz; suppresses switching noise from upstream DC/DC converters in mixed-signal systems. |
| Output Noise | 260 nV/√Hz at 10 kHz; minimizes interference in precision ADC references or audio codec supplies. |
| Thermal Shutdown | Activates at 160°C junction; latches off until die cools to ~150°C-prevents permanent damage during sustained overload. |
Pinout & Package
TC1015-2.85VCT713 is housed in a 3-pin SOT-223 package (JEDEC MO-178AA), with exposed thermal pad connected internally to GND for enhanced heat dissipation. Pin 1 = VIN, Pin 2 = GND, Pin 3 = VOUT; tab is electrically GND and must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Unregulated input supply | Accepts 2.7–6.0 V; minimum input must exceed 2.85 V + dropout (≥3.2 V typical at full load). |
| 2 (GND) | Ground reference and thermal path | Common return for input/output; exposed tab must be connected to ≥225 mm² top-side copper for θJA ≤53°C/W. |
| 3 (VOUT) | Regulated output | Delivers stable 2.85 V to load; requires ≥1 µF X5R/X7R ceramic capacitor directly at pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Rated for automotive applications (-40°C to +125°C); validated per stress test standards including HBM ±4 kV ESD. |
| Ultra-low noise | 260 nV/√Hz output noise enables use in precision analog circuits without additional filtering. |
| CMOS construction | Quiescent current stays constant at 80 µA regardless of load-critical for RTC backup and low-power sleep states. |
| Single-capacitor stability | Stable with only 1 µF output capacitor; eliminates need for costly low-ESR tantalum or complex compensation networks. |
| Fast load transient response | Maintains <2% output deviation during 100 mA → 500 mA step load changes-supports burst-mode processors. |
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 |
|---|---|---|---|
| MCP1700-2802E/TO | 280 mV max dropout at 250 mA; 1.6 µA quiescent current; 250 mA max output. | Lower IQ suits ultra-low-power wake-on-event designs; insufficient for 500 mA loads like motor drivers. | Select when battery life > output current; verify thermal margin for >300 mA continuous use. |
| TPS7A0528PDBVR | 250 mV dropout at 200 mA; 25 µA IQ; 200 mA max output; integrated enable pin. | Lacks AEC-Q100 rating; better for consumer IoT than automotive; requires external enable control. | Choose for cost-sensitive non-automotive designs needing fast enable/disable; not suitable for under-hood environments. |
Compared with MCP1700-2802E/TO and TPS7A0528PDBVR, TC1015-2.85VCT713 uniquely balances 500 mA capability, automotive qualification, and sub-100 µA quiescent current-making it the only option among the three viable for AEC-Q100-compliant systems demanding >300 mA at 2.85 V.

FAQ
What is the maximum input voltage rating for TC1015-2.85VCT713?
The absolute maximum input voltage for TC1015-2.85VCT713 is 6.0 V. Operation above this level risks permanent damage. The recommended operating range is 2.7 V to 6.0 V, with minimum input determined by dropout: for 500 mA load, VIN must be ≥3.2 V to maintain regulation. This constraint is critical when designing from partially discharged Li-ion or multi-cell alkaline sources.
Does TC1015-2.85VCT713 require an external capacitor for stability?
Yes, TC1015-2.85VCT713 requires a minimum 1 µF ceramic capacitor (X5R/X7R) placed directly between VOUT and GND. The capacitor must have ESR between 0.1 Ω and 5 Ω and resonant frequency above 1 MHz. No input capacitor is mandatory unless wiring exceeds 10 inches or battery source is used-then a 1 µF VIN-to-GND cap is recommended.
Is TC1015-2.85VCT713 AEC-Q100 qualified?
Yes, TC1015-2.85VCT713 is AEC-Q100 qualified (Grade 1: -40°C to +125°C). This is confirmed in Microchip's DS20001373D datasheet, which lists AEC-Q100 Automotive Qualified in the Features section and specifies junction temperature range matching Grade 1 requirements. The part undergoes stress testing per AEC-Q100 standards including HBM ±4 kV ESD.
What is the thermal shutdown behavior of TC1015-2.85VCT713?
TC1015-2.85VCT713 initiates thermal shutdown when junction temperature reaches 160°C, disabling output until die temperature falls to approximately 150°C. This hysteresis prevents oscillation during recovery. The shutdown threshold is fixed and unadjustable. Designers must ensure θJA (e.g., 59°C/W for SOT-223 on 100 mm² copper) keeps power dissipation within safe limits-calculated as PD ≈ (VIN – 2.85 V) × ILOAD.
Can TC1015-2.85VCT713 be used with ceramic capacitors only?
Yes, TC1015-2.85VCT713 is explicitly designed for stability with ceramic output capacitors ≥1 µF. Unlike older LDOs requiring tantalum or aluminum electrolytics, its CMOS architecture and internal compensation tolerate the low ESR of X5R/X7R ceramics. Microchip confirms compatibility in Section 3.1 ("Output Capacitor") of DS20001373D, noting aluminum types may freeze below -30°C-making ceramics preferred for wide-temperature operation.
