Product details
Overview
TC1016-2.8VCTTR from Microchip Technology is a fixed-output, 2.8 V CMOS low-dropout (LDO) linear voltage regulator in a 5-pin SOT-23 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 stable low-power regulation.
For engineers reviewing the TC1016-2.8VCTTR datasheet, TC1016-2.8VCTTR pinout, TC1016-2.8VCTTR application, or TC1016-2.8VCTTR equivalent, key selection criteria include shutdown current (0.05 µA typ.), wake-up time (10 µs typ.), ceramic capacitor compatibility (1 µF min), thermal/overcurrent protection, and pin compatibility with legacy bipolar LDOs in space-constrained designs.
Technical Context
The TC1016-2.8VCTTR uses a P-channel MOSFET pass element with internal bandgap reference and error amplifier feedback, enabling precise 2.8 V regulation across 2.7–6.0 V input range and 0–80 mA load. Its CMOS architecture eliminates base drive current, reducing quiescent consumption by ~60× versus bipolar LDOs.
Integrated features include logic-controlled shutdown (SHDN pin), thermal shutdown at 160°C (10°C hysteresis), current limiting (~120 mA short-circuit), and stability with low-ESR 1 µF ceramic output capacitors - eliminating need for external compensation or high-value electrolytics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V ±0.5% (typ.) - ensures tight regulation for sensitive analog/digital rails without external trimming. |
| Max Output Current | 80 mA - supports moderate-power microcontrollers, sensors, and RF front-ends in portable systems. |
| Dropout Voltage | 150 mV (typ.) at 80 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.2 V min) with margin. |
| Quiescent Current | 53 µA (typ.) - extends battery life in always-on or low-duty-cycle applications like pagers and medical monitors. |
| Shutdown Current | 0.05 µA (typ.) - reduces standby drain to negligible levels during system sleep modes. |
| Wake-Up Time | 10 µs (typ.) - allows rapid power cycling for burst-mode operation without voltage droop or delay penalties. |
| Input Voltage Range | 2.7 V to 6.0 V - accommodates wide battery chemistries (Li-ion, NiMH, alkaline) and unregulated DC supplies. |
Pinout & Package
TC1016-2.8VCTTR is housed in a RoHS-compliant 5-pin SOT-23 package (JEDEC MO-178AA), with 1.90 mm × 2.80 mm footprint and 1.18 mm height - optimized for high-density PCB layouts in handheld devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Unregulated supply input | Accepts 2.7–6.0 V input; requires ≥0.1 µF ceramic bypass close to pin for stability. |
| 2 (VOUT) | Regulated 2.8 V output | Delivers up to 80 mA; must be bypassed with ≥1 µF ceramic capacitor (X5R/X7R) for loop stability. |
| 3 (SHDN) | Active-high shutdown control | Drives regulator into 0.05 µA sleep mode when pulled below 15% VIN; tie to VIN if unused. |
| 4 (GND) | Ground reference terminal | Primary return path; connect directly to low-impedance ground plane to minimize noise and thermal rise. |
| 5 (NC) | No-connect terminal | Internally unconnected; leave floating - no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS P-channel pass transistor | Enables ultra-low quiescent current (53 µA) and eliminates base-drive losses inherent in bipolar LDOs. |
| 1 µF ceramic capacitor stability | Reduces BOM cost and board area vs. traditional tantalum/aluminum solutions; supports X5R/X7R dielectrics. |
| Thermal shutdown with hysteresis | Protects against sustained overload or poor heatsinking by disabling output at 160°C and re-enabling at ~150°C. |
| Fast 10 µs wake-up from shutdown | Minimizes latency in duty-cycled systems (e.g., wireless sensor nodes), preserving timing-critical responsiveness. |
| Pin-compatible upgrade path | Direct replacement for legacy bipolar LDOs in SOT-23 footprints - no PCB redesign needed for migration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2802E/TO | Same 2.8 V output, but 250 mA max output current and 1.6 µA quiescent current - higher IQ than TC1016-2.8VCTTR's 53 µA. | Preferred where higher load current is needed; less suitable for ultra-low-power sleep modes due to higher IQ. | Select MCP1700-2802E/TO only if >80 mA output capability is required and 1.6 µA IQ is acceptable. |
| TPS76328DBVR | 2.8 V fixed output, 150 mA max, 85 µA IQ, but requires 2.2 µF minimum output capacitance - not stable with 1 µF ceramic. | Used in TI-based designs with larger output caps; incompatible with space-constrained layouts relying on 1 µF stability. | Choose TPS76328DBVR only if existing design already uses ≥2.2 µF ceramic output caps and TI ecosystem alignment is critical. |
Compared with MCP1700-2802E/TO and TPS76328DBVR, the TC1016-2.8VCTTR delivers optimal balance of ultra-low quiescent current (53 µA), 1 µF ceramic stability, and SOT-23 pin compatibility - making it uniquely suited for battery life–critical, space-constrained portable systems where both efficiency and layout simplicity are mandatory.

FAQ
What is the maximum input voltage rating for TC1016-2.8VCTTR?
The absolute maximum input voltage for TC1016-2.8VCTTR is 6.0 V. Operation above this level risks permanent damage. The recommended operating input range is 2.7 V to 6.0 V, with minimum input determined by dropout voltage and output tolerance: VIN ≥ (2.8 V + 2.5%) + VDROPOUT. For reliable 2.8 V regulation at 80 mA, VIN should be ≥ 2.95 V.
Does TC1016-2.8VCTTR require an external resistor divider for output voltage setting?
No, TC1016-2.8VCTTR does not require an external resistor divider. It is a fixed-output regulator with the 2.8 V reference internally trimmed via laser calibration of the feedback resistor network. The output voltage is factory-set and non-adjustable - simplifying design and reducing component count.
Can TC1016-2.8VCTTR operate stably with a 1 µF ceramic output capacitor?
Yes, TC1016-2.8VCTTR is specifically designed for stability with a minimum 1 µF ceramic output capacitor (X5R or X7R dielectric). This is a key differentiator from many competing LDOs that require ≥2.2 µF or specific ESR ranges. The 1 µF requirement reduces board area and cost while maintaining phase margin across temperature and load.
What is the function of the NC pin on TC1016-2.8VCTTR in the SOT-23 package?
The NC (No Connect) pin on TC1016-2.8VCTTR (Pin 5 in SOT-23, Pin 2 in SC-70) is internally unconnected and serves no electrical function. It must be left floating - no routing, grounding, or termination is required. This pin exists for mechanical symmetry and package standardization, not circuit functionality.
How does the thermal shutdown feature behave in TC1016-2.8VCTTR?
TC1016-2.8VCTTR activates thermal shutdown when junction temperature exceeds ~160°C (typ.), turning off the P-channel MOSFET to halt power dissipation. It remains off until temperature drops to ~150°C (10°C hysteresis), then resumes regulation. This protects against sustained overload or inadequate PCB copper, but continuous cycling indicates insufficient thermal design - the device's max rated junction temperature is 125°C for continuous operation.
