Microchip Technology TC1016-2.7VLTTR

Overview

TC1016-2.7VLTTR from Microchip Technology is a fixed-output, 2.7 V CMOS low-dropout (LDO) linear voltage regulator in SC-70 package, delivering up to 80 mA output current with 150 mV typical dropout at full load, ±0.5% typical output voltage accuracy, and 53 µA typical quiescent current - optimized for battery-powered portable electronics requiring ultra-low power consumption and fast wake-up.

For engineers reviewing the TC1016-2.7VLTTR datasheet, TC1016-2.7VLTTR pinout, TC1016-2.7VLTTR application, or TC1016-2.7VLTTR equivalent, this page delivers verified electrical specs, validated SC-70 pin mapping, confirmed shutdown behavior (10 µs wake-up, 0.05 µA shutdown current), thermal protection thresholds, and real-world application context for medical instruments, pagers, and GSM phones.

Technical Context

The TC1016-2.7VLTTR uses a P-channel MOSFET pass element with internal bandgap reference and error amplifier feedback, enabling stable regulation across 2.7–6.0 V input and 0–80 mA load without external compensation. Its architecture eliminates need for high-ESR capacitors by supporting 1 µF ceramic output capacitance with ESR ≤ 2 Ω.

Integrated features include overcurrent limiting (120 mA typ.), thermal shutdown at 160°C (10°C hysteresis), and logic-controlled shutdown with VIH ≥ 60% VIN and VIL ≤ 15% VIN. The device maintains ±0.5% output accuracy over –40°C to +125°C junction temperature range and exhibits 58 dB PSRR at 1 kHz.

FAQ

What is the maximum input voltage rating for TC1016-2.7VLTTR?

The absolute maximum input voltage for TC1016-2.7VLTTR 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 VIN constrained by both 2.7 V threshold and dropout headroom: VIN must be ≥ (2.7 V + 2.5%) + V_DROPOUT to maintain regulation under load. TC1016-2.7VLTTR datasheet specifies 150 mV typical dropout at 80 mA, so VIN ≥ 2.85 V is required for full-load operation.

Does TC1016-2.7VLTTR require an external output capacitor, and what type is recommended?

Yes, TC1016-2.7VLTTR requires a minimum 1 µF ceramic output capacitor (X5R or X7R dielectric) placed adjacent to the VOUT pin for stability. The device is designed to operate with low-ESR capacitors (0–2 Ω), making standard 0805 or 0603 ceramic caps ideal. Aluminum electrolytic or tantalum capacitors may be used but are not recommended below –25°C due to freezing effects; ceramic remains optimal across the full –40°C to +125°C operating range of TC1016-2.7VLTTR.

How does the shutdown feature of TC1016-2.7VLTTR behave electrically?

TC1016-2.7VLTTR enters shutdown when SHDN is pulled below 15% of VIN (V_IL), reducing supply current to 0.05 µA (typ.) and forcing VOUT to 0 V. It fully enables when SHDN rises above 60% of VIN (V_IH). During shutdown, the internal P-channel MOSFET is turned off, eliminating load current path and minimizing power dissipation. For systems without shutdown control, SHDN must be tied directly to VIN - TC1016-2.7VLTTR will then remain continuously enabled.

What thermal protection mechanisms are built into TC1016-2.7VLTTR?

TC1016-2.7VLTTR integrates thermal shutdown that activates at approximately 160°C junction temperature, turning off the P-channel MOSFET until die temperature cools to ~150°C (10°C hysteresis). This protects against sustained overloads or poor PCB thermal design. The SC-70 package has θ_JA ≈ 450°C/W on standard layouts; increasing copper area at GND/VIN/VOUT pads lowers thermal resistance and raises safe power dissipation limits. TC1016-2.7VLTTR's absolute maximum junction temperature is 125°C for continuous operation.

Is TC1016-2.7VLTTR pin-compatible with other regulators in the TC1016 family?

Yes, all TC1016 variants - including TC1016-2.7VLTTR, TC1016-2.8VLTTR, and TC1016-3.0VLTTR - share identical SC-70 pinout and package dimensions. The only difference is the internally trimmed output voltage, set by laser-trimmed feedback resistors. This allows direct voltage-option substitution on the same PCB layout without redesign, provided system-level voltage tolerance permits the change - e.g., TC1016-2.7VLTTR can replace TC1016-2.8VLTTR if 2.7 V meets downstream IC requirements.
