Product details
Overview
NCP114ASN260T1G from onsemi is a 300 mA CMOS low-dropout linear regulator with fixed 2.6 V output, designed for noise-sensitive, space-constrained battery-powered systems. It delivers ±1% output accuracy at room temperature, 135 mV typical dropout at 300 mA (TSOP-5 package), and 75 dB PSRR at 1 kHz - enabling stable power for RF and analog circuitry in portable electronics.
For engineers reviewing the NCP114ASN260T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.7–5.5 V input range, ultra-low 50 µA quiescent current, thermal shutdown/current limit protection, and compatibility with 1 µF ceramic output capacitors - critical for compact, long-life portable designs.
Technical Context
The NCP114ASN260T1G uses a PMOS pass transistor architecture enabling low dropout and inherent reverse-current blocking. Its dynamic quiescent current adjustment minimizes IQ across load conditions, while internal bandgap reference and active discharge (enabled in 'A'-suffix variants) ensure precise regulation and controlled shutdown behavior.
It integrates thermal shutdown (160°C trip, 20°C hysteresis), output current limiting (600 mA typ.), and operates stably with minimal external components - requiring only 1 µF ceramic CIN and COUT. The TSOP-5 package supports thermal dissipation via exposed pad grounding and N/C pin (Pin 4) tie-down for enhanced heat removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6 V ±1% at room temperature - ensures stable biasing for 2.5–2.7 V logic rails and RF front-end ICs. |
| Max Output Current | 300 mA continuous - sufficient to power baseband processors, Bluetooth modules, or sensor subsystems. |
| Dropout Voltage | 160 mV typical at 300 mA (TSOP-5) - enables operation down to VIN = 2.76 V, extending battery runtime in single-cell Li-ion/Li-poly systems. |
| Quiescent Current | 50 µA typical at no-load - preserves battery life in always-on monitoring or sleep-mode applications. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from DC-DC converters feeding the LDO input, protecting sensitive analog/RF stages. |
| Stability | Guaranteed with ≥1 µF X5R/X7R ceramic output capacitor - eliminates need for tantalum or high-ESR caps, reducing BOM cost and footprint. |
| Protection | Thermal shutdown (160°C), current limit (600 mA typ.), and short-circuit robustness - prevents failure under fault conditions without external circuitry. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, with exposed pad (EPAD) tied to GND for thermal management. Pin 4 is Not Connected (N/C) and may be grounded to improve thermal dissipation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Regulated 2.6 V output; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 | IN | Input supply (1.7–5.5 V); needs local 1 µF ceramic decoupling to minimize noise coupling and trace inductance effects. |
| 3 | GND | Power ground reference; EPAD must be soldered directly to large GND copper plane for effective heat removal. |
| 4 | N/C | No internal connection; recommended to tie to GND to enhance thermal performance and mechanical reliability. |
| 5 | EN | Enable control: >0.9 V = ON, <0.4 V = OFF with active output discharge (100 Ω path to GND); internal 300 nA pull-down ensures default OFF state. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 50 µA typical at no-load - extends shelf life and operational time in battery-backed IoT sensors and wearables. |
| Active Output Discharge | 100 Ω discharge path when disabled - prevents floating outputs and ensures fast, predictable power-down sequencing in multi-rail systems. |
| Wide Input Range | 1.7–5.5 V operation - supports direct connection to single-cell Li-ion (2.7–4.2 V), LiFePO₄ (2.0–3.6 V), or USB-powered inputs. |
| High PSRR | 75 dB @ 1 kHz - maintains clean 2.6 V supply despite ripple from upstream switching regulators, critical for ADCs and RF transceivers. |
| Small-Cap Stability | Stable with 1 µF ceramic COUT - reduces solution size and cost vs. legacy LDOs requiring ≥10 µF tantalum or electrolytic capacitors. |
Applications
| Wireless Handset Power Management | Portable Medical Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2602E/MB | 250 mA max output, 170 mV dropout at 250 mA, 2 µA IQ - lower current, higher dropout, much lower quiescent current. | Suitable for ultra-low-power sub-100 mA sensor nodes; not recommended for 300 mA burst loads like scanner motors. | Select when IQ < 5 µA is mandatory and peak load ≤ 250 mA; verify thermal margin with 250 mW dissipation limit. |
| Torex XC6206P262MR-G | 300 mA output, 200 mV dropout at 300 mA, 1 µA IQ, no EN pin - identical current rating but higher dropout and no enable control. | Fits simple always-on 2.6 V rails where sequencing or standby mode is unnecessary. | Choose for cost-sensitive, non-sequenced applications; omit if system-level power gating or fast discharge is required. |
Compared with MCP1700T-2602E/MB and XC6206P262MR-G, the NCP114ASN260T1G uniquely balances 300 mA drive capability, 160 mV dropout, 50 µA IQ, and integrated EN-controlled active discharge - making it optimal for battery-powered systems requiring both performance and intelligent power management.

FAQ
What is the maximum input voltage rating for the NCP114ASN260T1G?
The NCP114ASN260T1G has an absolute maximum input voltage of 6 V. Operation is specified over 1.7 V to 5.5 V; exceeding 5.5 V risks damage even if below 6 V. For reliable long-term use, maintain VIN ≤ 5.5 V with appropriate derating for temperature and transient spikes.
Does the NCP114ASN260T1G include active output discharge, and how does it function?
Yes, the NCP114ASN260T1G includes active output discharge. When the EN pin is pulled below 0.4 V, the device disables regulation and connects the OUT pin to GND through an internal 100 Ω resistor, discharging the output capacitor rapidly. This feature is confirmed in the ordering table for 'A'-suffix TSOP-5 variants like NCP114ASN260T1G.
What output capacitor value and type are required for stable operation of the NCP114ASN260T1G?
The NCP114ASN260T1G is stable with a minimum 1 µF X5R or X7R ceramic capacitor on the OUT pin. Larger values (e.g., 4.7 µF) improve load transient response and high-frequency PSRR. Tantalum capacitors are not recommended due to high ESR and temperature-dependent impedance.
How does the thermal performance of the NCP114ASN260T1G compare between UDFN4 and TSOP-5 packages?
The TSOP-5 package (used by NCP114ASN260T1G) has a junction-to-air thermal resistance (RJA) of 236 °C/W on a 1 oz FR-4 board, versus 170 °C/W for UDFN4. While UDFN4 offers better thermal performance, TSOP-5 provides easier assembly and higher creepage/clearance - making NCP114ASN260T1G suitable for moderate-power applications with adequate PCB copper area.
Can the NCP114ASN260T1G be used with input voltages below 2.6 V?
No - the NCP114ASN260T1G requires VIN ≥ (VOUT + VDO). With a typical dropout of 160 mV at 300 mA, minimum functional VIN is ~2.76 V. Below this, regulation fails and output drops linearly with input. For sub-2.6 V operation, consider a lower-VOUT variant or a different LDO family.
