Product details

Overview

TC1017-2.6VLTTR from Microchip Technology is a fixed-output, CMOS low-dropout (LDO) linear voltage regulator in SC-70 package, delivering 2.6 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 including medical instruments and cellular handsets.

For engineers reviewing the TC1017-2.6VLTTR datasheet, TC1017-2.6VLTTR pinout, TC1017-2.6VLTTR application, or TC1017-2.6VLTTR equivalent, key selection criteria include shutdown current (0.05 µA typ), wake-up time (10 µs typ), ceramic capacitor compatibility (1 µF min), thermal shutdown threshold (160°C), and SC-70 footprint constraints.

Technical Context

The TC1017-2.6VLTTR uses a P-channel MOSFET pass element with internal bandgap reference and error amplifier feedback loop to maintain precise output regulation across 2.7–6.0 V input and 0–150 mA load. Its architecture eliminates external resistors by integrating a fixed voltage divider for the 2.6 V output setting.

It integrates overcurrent protection (120 mA short-circuit limit), thermal shutdown (160°C trip, 10°C hysteresis), and fast enable/disable control via SHDN pin with VIH ≥45% VIN and VIL ≤15% VIN - enabling reliable operation in transient-heavy battery-supplied systems without external supervision circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	2.6 V ±0.5% (typical accuracy enables stable MCU core supply without post-regulation trimming)
Max Output Current	150 mA (supports moderate-power peripherals like Bluetooth radios or sensor hubs)
Dropout Voltage	285 mV @ 150 mA (enables regulation down to VIN = 2.885 V, extending usable battery range)
Quiescent Current	53 µA (typ) @ full load - 60× lower than bipolar LDOs, directly extending battery life in sleep modes)
Shutdown Current	0.05 µA (typ) - reduces system standby power to nanoampere level during deep sleep)
Wake-Up Time	10 µs (typ) from SHDN assertion - supports rapid system wake cycles in responsive portable devices)
Input Voltage Range	2.7 V to 6.0 V - compatible with single Li-ion, dual alkaline, or regulated intermediate rails)

Pinout & Package

TC1017-2.6VLTTR is supplied in the 5-pin SC-70 package (JEDEC MO-203AA), offering 50% smaller footprint than SOT-23 while maintaining identical pin count and functional terminal mapping.

Pin/Terminal	Circuit Role	Design Meaning
1	SHDN	Active-high shutdown control: logic high (>45% VIN) enables regulator; logic low (<15% VIN) disables output and reduces I_IN to 0.05 µA
2	NC	No-connect terminal - must remain unconnected per design; no internal connection or function
3	GND	Ground reference for all internal circuitry; requires low-impedance connection to PCB ground plane for thermal and noise performance
4	VOUT	Regulated 2.6 V output; requires ≥1 µF ceramic capacitor (X5R/X7R) placed adjacent to pin for stability
5	VIN	Unregulated input supply (2.7–6.0 V); requires local 0.1–1 µF ceramic bypass capacitor near pin to suppress high-frequency noise

Key Features

Feature	Design Value
CMOS P-channel pass element	Enables ultra-low quiescent current (53 µA) and eliminates body diode reverse-current path in back-to-back configurations
1 µF ceramic capacitor stability	Reduces BOM cost and board area vs. traditional tantalum/low-ESR electrolytic solutions; supports X5R/X7R dielectrics
Integrated thermal shutdown	Auto-recovers from overload with 10°C hysteresis (160°C trip → 150°C restart), preventing permanent junction damage
Fixed 2.6 V output with ±0.5% accuracy	Eliminates external resistor network; ensures consistent supply for 2.5–2.7 V logic domains without calibration
Fast 10 µs wake-up from shutdown	Supports microsecond-scale power-state transitions in real-time embedded systems and wearables

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700-2602E/TT	Same manufacturer, same 2.6 V output, but SOT-23-5 package and 1.8 µA quiescent current - lower I_Q but higher dropout (600 mV @ 250 mA)	Preferred where ultra-low I_Q dominates over dropout or size; unsuitable for SC-70-constrained layouts	Select MCP1700-2602E/TT only if board space allows SOT-23 and standby current <2 µA is critical
NCP1117DT26RKG	Fixed 2.6 V bipolar LDO in SOT-223; 6 mA quiescent current, 1.2 V dropout, no shutdown pin	Used in non-battery applications with ample thermal margin and no need for enable control	Choose NCP1117DT26RKG only for cost-sensitive industrial supplies where shutdown and low I_Q are unnecessary

Compared with MCP1700-2602E/TT and NCP1117DT26RKG, TC1017-2.6VLTTR uniquely balances SC-70 miniaturization, 53 µA operating current, 285 mV dropout, and integrated shutdown - making it optimal for space- and battery-limited portable designs requiring fast enable timing and precision regulation.

FAQ

What is the maximum input voltage rating for TC1017-2.6VLTTR?

The absolute maximum input voltage for TC1017-2.6VLTTR is 6.0 V. Operation above this risks permanent damage. The recommended operating range is 2.7 V to 6.0 V, with minimum VIN constrained by both absolute threshold (≥2.7 V) and dropout headroom: VIN ≥ (2.6 V × 1.025) + V_DROPOUT, which calculates to ≥2.885 V at 150 mA load. Exceeding 6.0 V violates Absolute Maximum Ratings per DS21813F.

Does TC1017-2.6VLTTR require an external shutdown pull-up resistor?

No, TC1017-2.6VLTTR does not require an external pull-up on the SHDN pin. When unused, the SHDN pin may be directly tied to VIN to ensure permanent enable. Its input thresholds are ratiometric: VIH ≥45% VIN and VIL ≤15% VIN, eliminating dependency on fixed-voltage logic families. Internal circuitry ensures clean state transition without floating-input risk.

Can TC1017-2.6VLTTR operate stably with a 0.47 µF ceramic output capacitor?

No, TC1017-2.6VLTTR requires a minimum 1.0 µF ceramic output capacitor for guaranteed stability across all operating conditions. The datasheet specifies 1 µF as the lower bound for phase margin and transient response compliance. Using 0.47 µF may cause oscillation or excessive overshoot during load steps, particularly at high temperatures or near maximum load. X5R/X7R dielectrics are validated; Y5V is not recommended.

What is the thermal resistance (θ_JA) of TC1017-2.6VLTTR in its SC-70 package?

The junction-to-ambient thermal resistance (θ_JA) for TC1017-2.6VLTTR in the SC-70 package is 450°C/W under JEDEC J51-7 high-thermal-conductivity PCB layout conditions. This value assumes standard copper pour and trace width; actual θ_JA improves with larger copper area or thermal vias. At 150 mA and 3.3 V input, power dissipation is ~105 mW, resulting in ~47°C junction rise above ambient - well within the 125°C max rating.

Is TC1017-2.6VLTTR pin-compatible with bipolar LDOs such as LM2936 or LP2951?

TC1017-2.6VLTTR is marketed as a pin-compatible upgrade for certain bipolar LDOs in SC-70/SOT-23 footprints, but direct replacement requires verification of pin mapping and functionality. Unlike LP2951 (which has ADJ/VOUT/SENSE pins), TC1017-2.6VLTTR uses fixed 2.6 V output with SHDN/NC/GND/VOUT/VIN arrangement. It replaces legacy SC-70 bipolar regulators with identical pinout - not general-purpose adjustable LDOs. Always confirm pin function alignment before substitution.
