Microchip Technology TC1017-3.0VCTTR

Overview

TC1017-3.0VCTTR from Microchip Technology is a fixed-output, 3.0 V, 150 mA CMOS low-dropout (LDO) linear voltage regulator in SC-70 package. It delivers ±0.5% output voltage accuracy, 285 mV typical dropout at 150 mA, and consumes only 53 µA typical quiescent current - enabling extended battery life in portable systems.

For engineers reviewing the TC1017-3.0VCTTR datasheet, TC1017-3.0VCTTR pinout, TC1017-3.0VCTTR application, or TC1017-3.0VCTTR equivalent, key selection criteria include ultra-low shutdown current (0.05 µA), fast 10 µs wake-up time from shutdown, compatibility with 1 µF ceramic output capacitance, and integrated overcurrent/overtemperature protection for robust operation in space-constrained, battery-powered designs.

Technical Context

The TC1017-3.0VCTTR uses a P-channel MOSFET pass element, eliminating body diode reverse-current issues common in N-channel LDOs. Its internal error amplifier compares a precision bandgap reference with a resistive feedback network to maintain regulation across input voltages from 2.7 V to 6.0 V and load currents up to 150 mA.

It features active shutdown control via SHDN pin (VIH = 45% VIN, VIL = 15% VIN), thermal shutdown at 160°C (10°C hysteresis), and short-circuit current limiting to 120 mA (typ.) when VOUT < 0.5 V - all implemented without external components.

Key Specifications

Pinout & Package

TC1017-3.0VCTTR is supplied in the 5-pin SC-70 package (JEDEC MO-203AA), offering a 50% smaller footprint than SOT-23. Thermal resistance is 450°C/W (θJA), requiring careful PCB copper layout for power dissipation management above ~100 mW.

FAQ

What is the maximum input voltage rating for TC1017-3.0VCTTR?

The absolute maximum input voltage for TC1017-3.0VCTTR is 6.0 V. Operation above this level risks permanent damage. For reliable regulation at 3.0 V output, minimum input must satisfy VIN ≥ 3.075 V (3.0 V + 2.5% + dropout), and practical design should maintain VIN ≤ 5.5 V to limit power dissipation and junction temperature rise within the SC-70 package's thermal limits.

Does TC1017-3.0VCTTR require an input capacitor?

TC1017-3.0VCTTR does not require a minimum input capacitor for stability, but a 0.1 µF ceramic capacitor is recommended - especially when powered from high-impedance sources like batteries or long PCB traces - to reduce input impedance and improve high-frequency noise rejection. The device remains stable without it under low-source-impedance conditions.

Can TC1017-3.0VCTTR be used with tantalum output capacitors?

Yes, TC1017-3.0VCTTR is stable with tantalum output capacitors, provided their ESR falls within the 0–2 Ω range specified in the datasheet. However, ceramic X7R/X5R capacitors are preferred due to lower ESR (~50 mΩ), wider temperature stability, and absence of failure modes like surge-current-induced ignition seen in some tantalums.

What is the thermal shutdown behavior of TC1017-3.0VCTTR?

TC1017-3.0VCTTR initiates thermal shutdown when die temperature reaches ~160°C (typ.), turning off the P-channel pass transistor. It remains disabled until junction temperature cools to ~150°C (10°C hysteresis), then resumes regulation. This cycle prevents permanent damage but indicates inadequate PCB copper or excessive power dissipation - design must ensure steady-state TJ ≤ 125°C.

Is TC1017-3.0VCTTR pin-compatible with standard SOT-23-5 LDOs?

No - TC1017-3.0VCTTR uses the SC-70 package (MO-203AA) with pin 1 = SHDN, pin 2 = NC, pin 3 = GND, pin 4 = VOUT, pin 5 = VIN. Its pinout differs from both standard SOT-23-5 (e.g., pin 1 = VIN) and SC-70 variants like TC1017R. Direct replacement requires PCB layout revision; it is explicitly a pin-compatible upgrade for *bipolar* regulators, not generic SOT-23 footprints.
