Product details
Overview
NCP699SN14T1G from onsemi is a fixed-output CMOS low-dropout linear regulator delivering 1.4 V at up to 150 mA, featuring 40 µA typical ground current, 350 mV dropout at 150 mA, and ±2.0% output voltage accuracy - designed for battery-powered portable electronics requiring ultra-low quiescent power.
For engineers reviewing the NCP699SN14T1G datasheet, pinout, applications, or equivalent options, key selection criteria include TSOP-5 package compatibility, enable-input logic threshold (0.95 V high/0.3 V low), stability with 1 µF ceramic capacitors, and thermal shutdown protection at +160 °C.
Technical Context
The NCP699SN14T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and internal current/temperature limit circuits - enabling stable regulation without external feedback resistors. Its enable input supports sub-1 V logic control and must be tied to Vin if unused.
It operates across −40 °C to +85 °C ambient temperature, maintains regulation down to 2.1 V input (for 1.4 V output), and achieves 55 dB ripple rejection at 120 Hz - optimized for noise-sensitive analog and RF subsystems in handheld devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.4 V ±2.0% - eliminates need for external resistor divider; ensures consistent core/peripheral rail voltage under load and temperature variation. |
| Max Output Current | 150 mA - sufficient for powering baseband processors, sensors, or low-power microcontrollers in compact portable designs. |
| Dropout Voltage | 350 mV at 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (2.4 V min) with margin. |
| Ground Current | 40 µA typical (0–150 mA load) - minimizes battery drain during standby, critical for always-on sensor nodes or sleep-mode peripherals. |
| Enable Threshold | VEN(H) = 0.95 V, VEN(L) = 0.3 V - compatible with 1.2 V/1.8 V I/O domains; allows direct interfacing with low-voltage GPIOs without level shifters. |
| Capacitor Support | Stable with ≥1 µF ceramic or tantalum - reduces BOM cost and board area vs. regulators requiring high-ESR or minimum-Cout constraints. |
| Thermal Protection | Internal shutdown at ~160 °C - prevents permanent damage during transient overloads or poor PCB thermal design. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, surface-mount - optimized for space-constrained mobile PCB layouts with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Input supply connection; accepts 2.1–6.0 V - must be decoupled with ≥1 µF capacitor placed adjacent to pin 1. |
| 2 | Gnd | Power ground reference; requires low-impedance PCB pour to minimize noise coupling and ensure regulation accuracy. |
| 3 | Enable | Active-high digital control input; pulls device into <1 µA shutdown when ≤0.3 V - ties to Vin if unused to guarantee operation. |
| 4 | N/C | No internal connection - must remain unconnected; no routing or copper fill allowed on this pad. |
| 5 | Vout | Regulated 1.4 V output; requires ≥1 µF output capacitor close to pin 5 to maintain stability and suppress load transients. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ground current | 40 µA typical across full load and temperature range - extends battery life in intermittent-use devices like remote controls or wearables. |
| Low-noise regulation | 100 µVRMS output noise (100 Hz–100 kHz) - suitable for powering ADC references or RF front-end bias rails without added filtering. |
| Wide input voltage range | 2.1 V to 6.0 V input - supports direct connection to single Li-ion, dual alkaline, or USB-powered systems without pre-regulation. |
| Pb-free TSOP-5 package | RoHS-compliant, 0.95 mm pitch, 5-pin footprint - matches industry-standard SOT-23-5 land patterns for drop-in layout reuse. |
| Robust ESD protection | 2000 V HBM per MIL-STD-883 - withstands handling and assembly stresses without additional external protection diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1402E/TT | 300 mA rated, 2 µA quiescent current, SOT-23-3 package (no enable) | Lacks enable control and has different pinout - requires PCB redesign and firmware adaptation for shutdown sequencing. | Select only if higher current and lower IQ outweigh loss of enable functionality and package change. |
| Torex XC6206P142MR-G | 150 mA rated, 1 µA IQ, SOT-23-3 (no enable), ±2% accuracy, 350 mV dropout | No enable pin and 3-pin package - unsuitable for systems requiring dynamic power gating or multi-rail sequencing. | Choose only for cost-sensitive, always-on applications where enable control is unnecessary and footprint is constrained. |
Compared with MCP1700T-1402E/TT and XC6206P142MR-G, the NCP699SN14T1G uniquely combines 150 mA capability, 40 µA ground current, active-high enable with sub-1 V logic compatibility, and TSOP-5 packaging - making it the only option supporting both low-power standby and compact layout in portable designs requiring programmable rail control.

FAQ
What is the maximum input voltage rating for the NCP699SN14T1G?
The NCP699SN14T1G has a maximum input voltage rating of 6.0 V, with absolute minimum input of 2.1 V required to maintain 1.4 V output regulation. Exceeding 6.0 V may damage the device. The recommended operating range is 2.1 V to 5.5 V to ensure safe thermal margin and reliable enable functionality across temperature extremes.
Does the NCP699SN14T1G require external compensation components?
No, the NCP699SN14T1G does not require external compensation components. It is internally compensated and stable with 1 µF ceramic or tantalum output capacitors - eliminating the need for ESR tuning networks or additional passive components typically required by older LDO architectures.
What is the thermal shutdown threshold of the NCP699SN14T1G?
The NCP699SN14T1G features internal thermal protection that activates at approximately +160 °C junction temperature, turning off the output to prevent permanent damage. Recovery occurs automatically once the junction cools below the hysteresis threshold (~140 °C), and the device resumes regulation without external intervention.
Can the NCP699SN14T1G be used with a 1.2 V logic enable signal?
Yes, the NCP699SN14T1G can be directly driven by a 1.2 V logic signal because its enable input has a guaranteed turn-on threshold of 0.95 V (min) and turn-off threshold of 0.3 V (max). A 1.2 V GPIO meets the high-level requirement with 250 mV noise margin, ensuring reliable activation without level shifting.
Is the NCP699SN14T1G still in active production?
The NCP699SN14T1G was marked as discontinued in the February 2026 revision of the onsemi datasheet (Rev. 9); however, Aetrix Electronics maintains active inventory and offers lifecycle management support including last-time-buy planning, cross-reference guidance, and qualified alternatives for ongoing production programs.
