Product details
Overview
TC2015-3.0VCTTR from Microchip Technology is a 100 mA, 3.0 V fixed-output CMOS low-dropout (LDO) voltage regulator in a 5-pin SOT-23A package. It delivers ±0.4% output voltage accuracy, 140 mV typical dropout at 150 mA, 80 µA max supply current, and features shutdown control, reference bypass input for ultra-low-noise operation, and overcurrent/overtemperature protection. It serves as a precision post-regulator in battery-powered portable instrumentation.
For engineers reviewing the TC2015-3.0VCTTR datasheet, TC2015-3.0VCTTR pinout, TC2015-3.0VCTTR application, or TC2015-3.0VCTTR equivalent, key selection criteria include its 3.0 V fixed output, 100 mA output capability, 5-pin SOT-23A footprint, shutdown functionality with 60 µs wake-up response, and compatibility with 1 µF ceramic output capacitance.
Technical Context
The TC2015-3.0VCTTR is a CMOS-based LDO designed as a low-power, high-accuracy upgrade to bipolar regulators like the LP2980. Its architecture enables stable regulation with only 1 µF output capacitance and maintains constant 55 µA typical supply current independent of load.
It integrates a reference bypass terminal (Pin 4) that accepts 470 pF–0.01 µF capacitors to reduce internal reference noise, thereby improving PSRR (>55 dB at ≤1 kHz) and lowering output noise to 200 nV/√Hz. Shutdown is controlled via a CMOS-compatible SHDN pin with VIH = 60% VIN and VIL = 15% VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±0.4% (typical), enabling precise biasing of 3.0 V logic and analog circuitry |
| Max Output Current | 100 mA - supports moderate-power microcontrollers, sensors, and RF front-ends |
| Dropout Voltage | 140 mV (typ.) at 150 mA - allows operation down to VIN = 3.14 V while maintaining regulation |
| Supply Current | 55 µA (typ.), 80 µA (max) - minimizes quiescent drain in always-on battery systems |
| Shutdown Current | 0.05 µA (typ.), 0.5 µA (max) - enables deep-sleep power states without external switches |
| PSRR | 55 dB (≤1 kHz, CBYPASS = 0.01 µF) - suppresses switching noise from upstream SMPS stages |
| Operating Temp | –40°C to +125°C - qualified for industrial and automotive under-hood environments |
Pinout & Package
TC2015-3.0VCTTR is housed in a 5-lead plastic SOT-23A (EIAJ SC-74A) package with 0.95 mm pitch, 2.95 mm length, and 1.63 mm width. Thermal resistance θJA is 255°C/W on standard FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Unregulated input supply | Accepts 2.7–6.0 V input; requires ≥1 µF input capacitor if >10" from source or when using battery |
| 2 - GND | Ground reference | Common return for input/output capacitors and shutdown logic; critical for noise control |
| 3 - SHDN | Active-high shutdown control | Drives regulator into 0.5 µA sleep mode when pulled ≤15% VIN; wake-up time 60 µs (typ.) |
| 4 - Bypass | Reference bypass node | Connects 470 pF–0.01 µF ceramic cap to GND to reduce reference noise and improve PSRR |
| 5 - VOUT | Regulated 3.0 V output | Delivers up to 100 mA; stable with 1 µF ceramic output capacitor (ESR 0.01–5 Ω) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 55 µA typical supply current - extends battery life in always-on medical sensors |
| Reference bypass input | Pin 4 accepts 0.01 µF capacitor to cut output noise to 200 nV/√Hz and boost PSRR |
| Fast shutdown wake-up | 60 µs (typ.) VOUT rise time from shutdown - enables rapid system responsiveness |
| Thermal shutdown protection | Triggers at ~160°C die temperature and releases at ~150°C - prevents permanent damage |
| Stable with minimal capacitance | Works with 1 µF ceramic output cap - reduces BOM count and board area vs. older LDOs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | 300 mA output, 1.6 µA quiescent current, no bypass pin, SOT-23-5 | Higher current but no noise-reduction bypass capability; less suitable for RF/analog-sensitive designs | Select when higher output current is required and ultra-low noise is not critical |
| LP2980AIM5-3.0/NOPB | Bipolar process, 120 µA quiescent current, 350 mV dropout at 50 mA, no bypass pin | Higher dropout and supply current; lacks fast shutdown and thermal protection | Select only for legacy drop-in replacement where CMOS advantages are not needed |
Compared with MCP1700-3002E/TO and LP2980AIM5-3.0/NOPB, TC2015-3.0VCTTR uniquely balances 100 mA output, ultra-low 55 µA quiescent current, 140 mV dropout, and dedicated reference bypass - making it optimal for noise-critical, battery-constrained 3.0 V systems.

FAQ
What is the maximum input voltage rating for TC2015-3.0VCTTR?
The absolute maximum input voltage for TC2015-3.0VCTTR is 7.0 V. Operation above this level risks permanent device damage. The recommended operating input range is 2.7 V to 6.0 V, ensuring proper regulation across the full –40°C to +125°C junction temperature range. Exceeding 6.0 V may degrade long-term reliability even if within absolute maximum limits.
Does TC2015-3.0VCTTR require an external bypass capacitor for basic operation?
No, TC2015-3.0VCTTR operates fully functional without an external bypass capacitor. The Bypass pin (Pin 4) is optional: connecting a 0.01 µF ceramic capacitor improves PSRR and reduces output noise to 200 nV/√Hz, but leaving it unconnected still delivers full regulation, shutdown, and protection functionality.
Can TC2015-3.0VCTTR be used with ceramic output capacitors smaller than 1 µF?
No - TC2015-3.0VCTTR requires a minimum 1 µF ceramic (or tantalum/aluminum) output capacitor for stability across all load and temperature conditions. Using less capacitance risks oscillation or poor transient response. X5R/X7R dielectrics are recommended for stable ESR over temperature.
What is the thermal shutdown behavior of TC2015-3.0VCTTR?
TC2015-3.0VCTTR activates thermal shutdown at approximately 160°C junction temperature and remains off until the die cools to ~150°C. During shutdown, VOUT falls to zero and supply current drops to ≤0.5 µA. This hysteresis prevents cycling near the trip point and protects against sustained overtemperature conditions.
Is TC2015-3.0VCTTR pin-compatible with the LP2980 series?
Yes - TC2015-3.0VCTTR is explicitly designed as a pin-compatible upgrade to bipolar LDOs including the LP2980. It uses identical 5-pin SOT-23A pinout (VIN, GND, SHDN, Bypass, VOUT), enabling direct replacement without PCB changes while delivering lower quiescent current, lower dropout, and added features like reference bypass and faster shutdown response.
