Product details
Overview
NCP693DMN10TCG from onsemi is a 1.0 V fixed-output CMOS low-dropout linear voltage regulator designed for portable battery-powered systems requiring up to 1 A output current. It features ±1.0% output voltage accuracy over temperature, ultra-low 0.15–0.6 µA standby current with CE control, and integrated thermal shutdown and current limiting. It powers core logic rails in handheld instruments and camcorders.
For engineers reviewing the NCP693DMN10TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 1 A (0.45–1.45 V), enable threshold (0.4–1.0 V), PSRR of 70 dB at 1 kHz, and UDFN-6 (1.8×2 mm) thermal performance (RJA = 114 °C/W).
Technical Context
The NCP693DMN10TCG uses a PMOS pass transistor architecture enabling low dropout and fast transient response. Its internal block includes a precision voltage reference, error amplifier, auto-discharge circuit (D-version specific), and thermal shutdown with 165°C trip and 30°C hysteresis.
It operates across −40°C to +85°C ambient, supports input voltages from 1.6 V to 6.5 V, and delivers stable 1.0 V output with ≤120 mV load regulation (1 mA to 1 A). The D version adds faster turn-off speed and active discharge during disable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.0 V ±1.0% (0.985–1.015 V at 25°C; 0.960–1.027 V over −40°C to +85°C) |
| Max Output Current | 1 A continuous - supports high-current digital loads without external boost |
| Dropout Voltage | 0.45 V typ. at 300 mA; 1.0 V typ. at 1 A - enables operation from single Li-ion or dual alkaline cells |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters |
| Standby Current | 0.15–0.6 µA with CE = 0 V - extends battery life in sleep modes |
| Thermal Shutdown | 165°C trip with 30°C hysteresis - prevents permanent damage during overload or poor PCB heatsinking |
| Enable Threshold | VTH(HI) = 1.0 V min., VTH(LO) = 0.4 V max. - compatible with 1.8 V and 3.3 V GPIOs |
Pinout & Package
Package: UDFN-6 (1.8 mm × 2.0 mm, 0.5 mm pitch), exposed thermal pad (EP = GND), RoHS-compliant Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Vout | Dual output pins reduce IR drop and improve current sharing for 1 A load |
| 3, EP | GND | Power ground and thermal path - EP must be soldered to PCB copper for RJA compliance |
| 4 | CE | Active-high enable - pull low to disable regulator and activate auto-discharge (D version only) |
| 5, 6 | Vin | Dual input pins lower trace impedance and enhance PSRR by reducing supply loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Actively discharges output capacitor when CE = low - prevents residual voltage from powering downstream circuits |
| Ultra-low quiescent current | 65–90 µA operating / 0.15–0.6 µA standby - minimizes no-load battery drain in always-on devices |
| High-accuracy reference | ±1.0% initial tolerance and <100 ppm/°C tempco - eliminates need for external trimming in precision rails |
| Robust protection suite | Integrated current limit (250 mA short-circuit), thermal shutdown, and ESD rating >2 kV HBM - reduces external protection components |
| Low-noise output | 45 µVRMS (10 Hz–100 kHz) - suitable for noise-sensitive analog and RF subsystems |
Applications
| Hand-Held Instruments | Camcorders & Cameras |
|---|---|
Use Scenario: Portable multimeters and thermal imagers powered by two AA batteries. IC Role / Device Role / Timing Role: Primary 1.0 V core supply for microcontroller and ADC subsystems.

Use Value: 0.15 µA standby current extends shelf life; auto-discharge prevents phantom power draw after shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1826T-1002E/DB | 1.0 V, 1 A, 300 mV dropout @ 1 A; no auto-discharge; SOT-23-5 package | Lacks fast turn-off and output discharge - unsuitable where residual Vout must be cleared | Select when board space permits SOT-23 and auto-discharge is not required |
| TLS850F1BTTA1 | 1.0 V, 500 mA, automotive-grade AEC-Q100; higher dropout (600 mV @ 500 mA); TSON-10 | Rated for −40°C to +150°C junction; lacks CE pin and auto-discharge | Select only for automotive environments requiring extended temperature range and qualification |
Compared with MCP1826T-1002E/DB and TLS850F1BTTA1, the NCP693DMN10TCG uniquely combines 1 A capability, sub-µA standby, auto-discharge, and UDFN-6 footprint - making it optimal for space-constrained, battery-sensitive consumer electronics where rapid, clean shutdown is mandatory.

FAQ
What is the maximum input voltage rating for the NCP693DMN10TCG?
The NCP693DMN10TCG has an absolute maximum input voltage (Vin) rating of 7 V per its datasheet, but the recommended operating range is 1.6 V to 6.5 V. Exceeding 6.5 V risks exceeding internal PMOS gate oxide limits and may degrade long-term reliability. Always maintain ≥100 mV margin between Vin and maximum rated value in production designs.
Does the NCP693DMN10TCG require external capacitors, and what values are recommended?
Yes, the NCP693DMN10TCG requires both input (Cin) and output (Cout) decoupling capacitors. The datasheet specifies minimum 2.2 µF ceramic or tantalum for each, placed as close as possible to the respective pins. Larger values improve transient response and PSRR, but tantalum capacitors must be selected carefully to avoid oscillation due to ESR sensitivity.
How does the auto-discharge feature work in the NCP693DMN10TCG?
The NCP693DMN10TCG's auto-discharge feature activates automatically when the CE pin is pulled low. An internal NMOS transistor connects Vout to GND, rapidly discharging the output capacitor. This prevents residual voltage from powering downstream circuitry after shutdown - a critical requirement in systems with strict zero-power states or safety interlocks.
What is the thermal resistance (RJA) of the NCP693DMN10TCG, and how is it measured?
The NCP693DMN10TCG has a typical junction-to-ambient thermal resistance (RJA) of 114 °C/W, measured on a standard 80 mm × 80 mm × 1.5 mm FR4 PCB with 1 oz copper and 100 mm² copper pour under the exposed pad. Achieving this value requires full soldering of the EP pad to the PCB ground plane; insufficient thermal land area will increase actual RJA and reduce safe operating current.
Is the NCP693DMN10TCG pin-compatible with other variants in the NCP693 family?
Yes, all NCP693 variants - including NCP693DMN08TCG, NCP693DMN12TCG, and NCP693HMN10TCG - share identical UDFN-6 (1.8×2 mm) pinout and footprint. Only the output voltage and auto-discharge functionality differ between D and H versions; electrical and mechanical compatibility allows direct substitution in layouts where voltage and enable behavior match system requirements.
