Product details
Overview
TC1017-4.0VLTTR from Microchip Technology is a fixed-output, CMOS low-dropout (LDO) linear voltage regulator in SC-70 package, delivering 4.0 V ±0.5% output with 150 mA rated current, 285 mV typical dropout at 150 mA, and 53 µA typical quiescent current - optimized for battery-powered portable electronics requiring precision regulation and ultra-low power consumption.
For engineers reviewing the TC1017-4.0VLTTR datasheet, TC1017-4.0VLTTR pinout, TC1017-4.0VLTTR application, or TC1017-4.0VLTTR equivalent, key selection criteria include shutdown current (0.05 µA typ), ceramic capacitor compatibility (1 µF min), thermal shutdown threshold (160°C), and SC-70 footprint constraints for space-constrained PCB layouts.
Technical Context
The TC1017-4.0VLTTR uses a P-channel MOSFET pass element enabling stable operation with only 1 µF ceramic output capacitance and supporting input voltages from 2.7 V to 6.0 V. Its internal bandgap reference and error amplifier deliver ±0.5% output accuracy over temperature and load.
It integrates active protection features including overcurrent limiting (120 mA typ during short-circuit), thermal shutdown (160°C trip, 10°C hysteresis), and fast wake-up (10 µs typ) from shutdown mode - all implemented without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.0 V ±0.5% (typical accuracy enables stable MCU core or sensor bias without post-regulation trimming) |
| Max Output Current | 150 mA (supports moderate-power peripherals like RF modules or display drivers) |
| Dropout Voltage | 285 mV @ 150 mA (enables regulation down to VIN = 4.285 V, extending battery runtime in 4.2 V Li-ion systems) |
| Quiescent Current | 53 µA (typ) across full 0–150 mA load range - reduces standby power loss by >98% vs bipolar LDOs) |
| Shutdown Current | 0.05 µA (typ) - preserves battery life during deep sleep modes in portable medical or IoT devices) |
| Input Voltage Range | 2.7 V to 6.0 V (covers single-cell Li-ion, dual-cell alkaline, and USB-powered applications) |
| Thermal Shutdown | 160°C trip with 10°C hysteresis (prevents permanent damage during transient overload or poor heatsinking) |
Pinout & Package
TC1017-4.0VLTTR is supplied in a 5-pin SC-70 package (JEDEC MO-203AA), offering 50% smaller footprint than SOT-23. Pin 1 is SHDN, Pin 2 is NC (no connect), Pin 3 is GND, Pin 4 is VOUT, and Pin 5 is VIN - verified per DS21813F-page 9 pin function table and Figure 4-1 block diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (SHDN) | Shutdown control input | Logic-high (>45% VIN) enables regulation; logic-low (<15% VIN) disables output and reduces supply current to 0.05 µA |
| Pin 2 (NC) | No-connect terminal | Internally unconnected - must remain floating or grounded per layout best practice; no electrical function |
| Pin 3 (GND) | Ground reference | Primary return path for load current and internal bias; requires low-impedance connection to ground plane |
| Pin 4 (VOUT) | Regulated output | Delivers stable 4.0 V ±0.5%; requires ≥1 µF ceramic capacitor to GND for stability and transient response |
| Pin 5 (VIN) | Unregulated input | Accepts 2.7–6.0 V input; bypassed with ≥0.1 µF ceramic capacitor to suppress high-frequency noise and ensure stability |
Key Features
| Feature | Design Value |
|---|---|
| CMOS P-channel pass element | Enables ultra-low quiescent current (53 µA) and eliminates body diode reverse conduction in back-to-back configurations |
| 1 µF ceramic capacitor stability | Reduces BOM count and board area vs. traditional LDOs requiring ≥10 µF tantalum or electrolytic capacitors |
| 10 µs wake-up time from shutdown | Supports rapid system wake-up in duty-cycled applications (e.g., wireless sensor nodes) without output overshoot or settling delay |
| Integrated overtemperature protection | Automatically disables output at 160°C junction temperature, preventing thermal runaway during sustained overload |
| ±0.5% output voltage accuracy | Meets tight tolerance requirements for analog sensor biasing, ADC reference supplies, and low-voltage microcontroller cores |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-4002E/MB | Same SC-70 package, 4.0 V output, but lower max current (250 mA vs 150 mA); 1.6 µA quiescent current (lower than TC1017-4.0VLTTR's 53 µA) | Optimized for ultra-low-IQ applications; less suitable for 150 mA continuous loads due to higher dropout at full load | Select when standby current dominates design priority and peak load ≤100 mA |
| TPS76340DBVR | SOT-23-5 package, 4.0 V output, 150 mA rating, but bipolar process - 90 µA quiescent current (higher than TC1017-4.0VLTTR's 53 µA) | Higher thermal resistance (θJA = 260°C/W vs SC-70's 450°C/W) limits power dissipation in confined layouts | Select when existing SOT-23 footprint reuse is required and 37 µA higher IQ is acceptable |
Compared with MCP1700T-4002E/MB and TPS76340DBVR, TC1017-4.0VLTTR uniquely balances 150 mA capability, 53 µA quiescent current, and SC-70 footprint - making it optimal for space-constrained, battery-powered systems needing both moderate current and long standby life.

FAQ
What is the output voltage tolerance of the TC1017-4.0VLTTR?
The TC1017-4.0VLTTR provides a nominal 4.0 V output with ±0.5% typical accuracy over temperature and load, as specified in DS21813F Electrical Characteristics table. This corresponds to a 4.0 V ±20 mV window under standard test conditions (TA = +25°C, IL = 100 µA, CL = 1.0 µF), ensuring reliable operation for precision analog and digital loads without external trimming.
Does the TC1017-4.0VLTTR require an input capacitor?
Yes - the TC1017-4.0VLTTR requires a minimum 0.1 µF ceramic input capacitor placed close to the VIN pin to ensure stability, especially when powered from high-impedance sources like batteries or long PCB traces. The datasheet recommends larger values (e.g., 1 µF) to improve high-frequency noise rejection and transient response, particularly in noisy environments such as cellular handsets where TC1017-4.0VLTTR is commonly deployed.
What is the maximum allowable input voltage for the TC1017-4.0VLTTR?
The absolute maximum input voltage for the TC1017-4.0VLTTR is 6.0 V, as defined in the Absolute Maximum Ratings table. Operation above this level risks permanent device damage. For reliable continuous operation, the input must also satisfy VIN ≥ (4.0 V + 2.5%) + VDROPOUTMAX - meaning VIN must be ≥ approximately 4.285 V at 150 mA load to maintain regulation, per Note 1 in the Electrical Characteristics section.
Can the TC1017-4.0VLTTR operate with a 1 µF ceramic output capacitor?
Yes - the TC1017-4.0VLTTR is explicitly designed to be stable with a minimum 1 µF ceramic output capacitor (X5R or X7R dielectric), as confirmed in the General Description and Section 4.2. This eliminates need for larger, higher-ESR tantalum or aluminum electrolytic capacitors, reducing cost, size, and improving low-temperature performance - a key advantage in portable applications where TC1017-4.0VLTTR is used.
How does the shutdown feature of the TC1017-4.0VLTTR work?
The TC1017-4.0VLTTR enters shutdown when the SHDN pin voltage falls below 15% of VIN (VIL), reducing supply current to 0.05 µA typical and pulling VOUT to 0 V. It fully enables when SHDN rises above 45% of VIN (VIH). For unused shutdown, tie SHDN directly to VIN - no external pull-up resistor is needed. This behavior is validated in Section 3.1 and Figure 4-2 of the TC1017-4.0VLTTR datasheet.
