Product details
Overview
TC1016-4.0VLTTR from Microchip Technology is a fixed-output, 4.0 V CMOS low-dropout linear regulator in SC-70 package, delivering up to 80 mA with ±0.5% output voltage accuracy, 150 mV typical dropout at full load, and 53 µA typical quiescent current - designed for battery-powered portable electronics requiring stable, ultra-low-power voltage regulation.
For engineers reviewing the TC1016-4.0VLTTR datasheet, TC1016-4.0VLTTR pinout, TC1016-4.0VLTTR application, or TC1016-4.0VLTTR equivalent, this page delivers verified electrical specs, validated SC-70 pin mapping, real-world use cases in medical instruments and pagers, and two confirmed alternative LDOs with documented functional trade-offs.
Technical Context
The TC1016-4.0VLTTR employs a P-channel MOSFET pass element enabling low dropout and fast wake-up (10 µs typ.), with internal bandgap reference and error amplifier for precision regulation. Its shutdown control (SHDN) reduces supply current to 0.05 µA while disabling VOUT.
Stability is guaranteed with only 1 µF ceramic output capacitance (ESR 0–2 Ω), and protection includes overcurrent limiting (120 mA typ.) and thermal shutdown at 160°C with 10°C hysteresis - all integrated without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.0 V ±0.5% (typ.), stable across –40°C to +125°C junction temperature |
| Max Output Current | 80 mA continuous - sufficient for microcontroller cores, sensors, and RF front-ends in portable systems |
| Dropout Voltage | 150 mV (typ.) at 80 mA - enables regulation down to VIN = 4.15 V, extending battery runtime |
| Quiescent Current | 53 µA (typ.) active, 0.05 µA (typ.) in shutdown - minimizes standby drain in always-on devices |
| Wake-Up Time | 10 µs (typ.) from shutdown - supports rapid power cycling in burst-mode communication systems |
| Input Voltage Range | 2.7 V to 6.0 V - compatible with single-cell Li-ion (3.0–4.2 V), dual-cell alkaline, and regulated 5 V rails |
| PSRR | 58 dB at 1 kHz - suppresses switching noise from DC/DC converters upstream of the LDO |
Pinout & Package
TC1016-4.0VLTTR is packaged in a 5-pin SC-70 (lead pitch 0.65 mm, footprint ~1.8 × 1.35 mm), offering 50% area reduction versus SOT-23. The package is Pb-free, RoHS-compliant, and marked "AP" per Microchip's voltage code table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Logic-high (>60% VIN) enables regulation; logic-low (<15% VIN) disables output and cuts supply current to 0.05 µA |
| 2 (NC) | No-connect terminal | Internally unconnected - must be left floating or tied to GND; no electrical function |
| 3 (GND) | Ground reference | Primary return path for load current and bias; requires low-impedance connection to PCB ground plane |
| 4 (VOUT) | Regulated output | Delivers stable 4.0 V; requires ≥1 µF ceramic capacitor (X5R/X7R) placed adjacent to pin for stability |
| 5 (VIN) | Unregulated input | Accepts 2.7–6.0 V; bypassed with ≥0.1 µF ceramic capacitor near pin to suppress high-frequency noise |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 53 µA typical across full 80 mA load range - extends battery life >60× vs. bipolar LDOs |
| Minimal external components | Stable with only 1 µF ceramic output cap - eliminates need for ESR-tuned tantalum or electrolytic capacitors |
| Fast enable/disable response | 10 µs wake-up + 32 µs settling time - enables microsecond-scale power gating in sleep/wake cycles |
| Integrated protection | Current limit (120 mA typ.) and thermal shutdown (160°C trip, 10°C hysteresis) - prevents damage during fault conditions without external circuitry |
| Pin-compatible upgrade path | Direct replacement for legacy bipolar regulators in SC-70 footprint - no PCB redesign required |

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/TT | Same 4.0 V output, 250 mA rating, but 1.6 µA quiescent current - 33× lower than TC1016-4.0VLTTR | Better suited for ultra-long-life applications (e.g., IoT sensors), but higher dropout (600 mV @ 250 mA) | Select when lowest possible IQ dominates over dropout and cost; verify thermal margin at 80 mA due to higher RDS(on) |
| NCP1117DT40RKG | 4.0 V fixed output, 1 A rating, but 6 mA quiescent current - 113× higher than TC1016-4.0VLTTR | Designed for high-current industrial loads; requires minimum 10 µF output capacitance and has slower transient response | Select only when >100 mA peak current is needed; avoid in battery-critical designs due to excessive standby drain |
Compared with MCP1700T-4002E/TT and NCP1117DT40RKG, the TC1016-4.0VLTTR uniquely balances ultra-low IQ (53 µA), low dropout (150 mV), and SC-70 space efficiency - making it optimal for compact, battery-constrained portable systems where moderate current and fast enable timing are essential.

FAQ
What is the maximum input voltage rating for the TC1016-4.0VLTTR?
The TC1016-4.0VLTTR has an absolute maximum input voltage of 6.0 V. Operation above this level risks permanent damage. The recommended operating range is 2.7 V to 6.0 V, with minimum input determined by dropout: VIN must be ≥ 4.15 V (4.0 V + 150 mV) to maintain regulation at 80 mA load. Thermal limits may further constrain practical VIN based on ambient temperature and PCB copper area.
Does the TC1016-4.0VLTTR require an input capacitor, and if so, what value is recommended?
Yes, the TC1016-4.0VLTTR requires an input capacitor for stability, especially when powered from high-impedance sources like batteries or long PCB traces. A minimum of 0.1 µF ceramic capacitor is recommended, placed as close as possible to the VIN pin. Larger values (e.g., 1 µF) improve high-frequency noise rejection and transient response, particularly when paired with the required 1 µF output capacitor.
Can the TC1016-4.0VLTTR be used without connecting the SHDN pin?
Yes - the TC1016-4.0VLTTR operates continuously when SHDN is tied directly to VIN. This configuration disables shutdown functionality but ensures full regulation. Leaving SHDN floating is not recommended, as it may cause erratic enable/disable behavior due to noise coupling. For unused shutdown, connect SHDN to VIN via a direct trace or 10 kΩ pull-up resistor.
What is the thermal shutdown threshold and hysteresis of the TC1016-4.0VLTTR?
TC1016-4.0VLTTR activates thermal shutdown when die temperature reaches approximately 160°C (typ.), turning off the P-channel MOSFET to halt power dissipation. It remains disabled until junction temperature falls to ~150°C (10°C hysteresis), at which point regulation resumes. This protects against sustained overtemperature events but does not replace proper thermal design - maximum steady-state junction temperature remains 125°C.
Is the TC1016-4.0VLTTR compatible with ceramic output capacitors having ESR below 10 mΩ?
Yes - the TC1016-4.0VLTTR is explicitly designed for stability with low-ESR ceramic capacitors, including X5R and X7R types with ESR as low as 50 mΩ (typical for 1 µF 0805). The device's internal compensation supports ESR values from 0 Ω to 2 Ω, making it fully compatible with modern low-ESR ceramics and eliminating the need for series resistors or tantalum alternatives.
