Product details
Overview
TC2015-2.7VCTTR from Microchip Technology is a 100 mA, fixed-output CMOS low-dropout (LDO) voltage regulator with shutdown control and reference bypass input, delivering ±0.4% output voltage accuracy at 2.7 V, 140 mV typical dropout at full load, and 80 µA maximum supply current. It operates across –40°C to +125°C and targets battery-powered medical instruments and portable computing systems requiring ultra-low-noise regulation.
For engineers reviewing the TC2015-2.7VCTTR datasheet, TC2015-2.7VCTTR pinout, TC2015-2.7VCTTR application, or TC2015-2.7VCTTR equivalent, key selection criteria include its 100 mA output capability, 2.7 V fixed output, SOT-23A package compatibility, fast 60 µs wake-up time, and support for 1 µF ceramic output capacitance without stability compensation.
Technical Context
The TC2015-2.7VCTTR implements a CMOS-based LDO architecture optimized for low quiescent current and high PSRR-achieving 55 dB at ≤1 kHz with 0.01 µF bypass capacitor. Its internal reference bypass input enables ultra-low-noise operation (200 nV/√Hz at 10 kHz), while thermal shutdown (160°C) and overcurrent protection ensure robustness in compact embedded systems.
Unlike bipolar LDOs, it maintains constant 55 µA typical supply current independent of load, and achieves stable regulation with only 1 µF output capacitance (ESR 0.01–5 Ω). The device supports logic-level shutdown control (VIH = 60% VIN, VIL = 15% VIN) and enters sub-0.5 µA shutdown mode with zero VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±0.4% (typical); ensures precise biasing for 2.7 V–tolerant microcontrollers and sensors. |
| Max Output Current | 100 mA; sufficient for powering single-core MCUs, RF transceivers, or analog front-ends in portable devices. |
| Dropout Voltage | 140 mV (typ.) @ 100 mA; enables regulation from 2.84 V input, critical for single-cell Li-ion or alkaline battery systems. |
| Supply Current | 55 µA (typ.), 80 µA (max); reduces standby power loss by >20× vs. bipolar LDOs, extending battery life. |
| PSRR | 55 dB @ ≤1 kHz with 0.01 µF bypass cap; suppresses switching noise from upstream SMPS in mixed-signal designs. |
| Shutdown Current | 0.5 µA (max); enables deep-sleep modes in IoT edge nodes without external load switches. |
| Operating Temp | –40°C to +125°C; qualified for automotive cabin, industrial control, and medical-grade portable equipment. |
Pinout & Package
TC2015-2.7VCTTR is housed in a 5-pin SOT-23A (EIAJ SC-74A) package with 220°C/W junction-to-air thermal resistance on standard FR4 PCBs. Pin 1 is VIN; orientation follows standard EIAJ tape-and-reel marking (marking side up, pin 1 top-left).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Unregulated input supply | Accepts 2.7–6.0 V input; requires ≥1 µF ceramic decoupling close to pin for transient immunity. |
| GND (Pin 2) | Ground reference | Common return for input/output capacitors and bypass cap; must connect to low-impedance ground plane. |
| SHDN (Pin 3) | Logic-controlled enable | Active-high shutdown: VIH ≥60% VIN enables regulator; VIL ≤15% VIN forces 0.5 µA shutdown state. |
| Bypass (Pin 4) | Reference noise filter | Connects 470 pF–0.01 µF ceramic cap to GND to reduce output noise to 200 nV/√Hz and boost PSRR. |
| VOUT (Pin 5) | Regulated output | Delivers stable 2.7 V ±0.4%; requires ≥1 µF ceramic output cap with ESR 0.01–5 Ω for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-noise regulation | 200 nV/√Hz output noise at 10 kHz with 470 pF bypass cap-enables clean power for ADCs and RF ICs. |
| Fast wake-up response | 60 µs typical time to reach 95% of 2.7 V after SHDN assertion-supports rapid system boot and duty-cycled operation. |
| Thermal shutdown protection | Triggers at 160°C die temperature and releases at ~150°C-prevents permanent damage during overload or poor heatsinking. |
| Low-ESR capacitor compatibility | Stable with 1 µF ceramic output caps (X5R/X7R); eliminates need for costly tantalum or electrolytic alternatives. |
| Pin-compatible upgrade path | Direct replacement for LP2980-series bipolar LDOs-no PCB redesign needed when migrating to lower IQ solutions. |

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 | 300 mA output, 1.6 µA quiescent current, no bypass input, 600 mV dropout at 250 mA | Lacks reference bypass for ultra-low-noise apps; better suited for higher-current, lower-IQ general-purpose use | Select when >100 mA load or lowest possible IQ is required, but noise sensitivity is not critical |
| LP2980AIM5-2.7/NOPB | Bipolar process, 120 µA IQ, 120 mV dropout at 50 mA, no bypass input, ±1% accuracy | Higher IQ and lower accuracy; lacks shutdown control and bypass functionality | Choose only for legacy drop-in where CMOS features are unnecessary and cost is primary constraint |
Compared with MCP1700-2702E/TO and LP2980AIM5-2.7/NOPB, TC2015-2.7VCTTR uniquely balances 100 mA capability, ±0.4% accuracy, ultra-low noise via bypass, and fast 60 µs wake-up-making it optimal for precision battery-powered instrumentation where both performance and power efficiency are non-negotiable.

FAQ
What is the minimum input voltage required for TC2015-2.7VCTTR to regulate properly?
The TC2015-2.7VCTTR requires VIN ≥ 2.7 V and VIN ≥ VOUT + VDROPOUT. With a typical dropout of 140 mV at 100 mA, the minimum functional input is 2.84 V. Per datasheet Note 1, the absolute minimum VIN is 2.7 V-but operation below VOUT + dropout will cause output collapse. Always verify margin under worst-case load and temperature conditions for TC2015-2.7VCTTR.
Can TC2015-2.7VCTTR operate with a 0.47 µF output capacitor?
No-TC2015-2.7VCTTR requires a minimum 1 µF output capacitor (ceramic, tantalum, or aluminum) for guaranteed stability across all operating conditions. Using 0.47 µF violates the datasheet specification and may cause oscillation or poor transient response. The 1 µF value is validated for ESR between 0.01 Ω and 5 Ω, and X5R/X7R dielectrics are recommended for temperature stability in TC2015-2.7VCTTR designs.
Does TC2015-2.7VCTTR support adjustable output voltage?
No-TC2015-2.7VCTTR is a fixed-output regulator with factory-trimmed 2.7 V output. For adjustable versions, Microchip recommends the TC1070, TC1071, or TC1187 families, which feature external resistor-divider feedback. The TC2015-2.7VCTTR pinout and internal architecture do not support external voltage programming; attempting to modify VOUT externally will result in regulation failure or damage.
How does the Bypass pin improve noise performance in TC2015-2.7VCTTR?
The Bypass pin (Pin 4) connects to an internal bandgap reference node. Adding a 0.01 µF ceramic capacitor from Bypass to GND shunts high-frequency noise on the reference, reducing output voltage noise to 200 nV/√Hz at 10 kHz and improving PSRR by up to 20 dB below 100 kHz. Omitting the bypass cap degrades noise performance but does not affect basic regulation-making TC2015-2.7VCTTR flexible for cost-sensitive vs. noise-critical designs.
Is TC2015-2.7VCTTR pin-compatible with LP2980IM5-2.7/NOPB?
Yes-TC2015-2.7VCTTR uses the same 5-pin SOT-23A (SC-74A) footprint and identical pinout (VIN-GND-SHDN-BYPASS-VOUT) as LP2980IM5-2.7/NOPB, enabling direct PCB replacement. However, TC2015-2.7VCTTR adds shutdown control and bypass functionality not present in the LP2980, so existing designs must route SHDN and optionally connect the bypass capacitor to realize full benefits of TC2015-2.7VCTTR.
