Product details
Overview
NCP693HMN25TCG from onsemi is a fixed-output, 2.5 V, 1 A CMOS low-dropout linear voltage regulator in a 6-pin DFN (1.8×2 mm, 0.5 mm pitch) package. It features ±1.0% output voltage accuracy over −40°C to +85°C, ultra-low 65–90 µA quiescent current, and integrated thermal shutdown and current limiting. It is designed for high-efficiency power regulation in space-constrained portable battery-powered systems such as cameras and handheld instruments.
For engineers reviewing the NCP693HMN25TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 1 A load (0.500 V typ), enable-controlled standby mode (0.15–0.6 µA), PSRR of 70 dB at 1 kHz, and compatibility with ceramic output capacitors ≥2.2 µF.
Technical Context
The NCP693HMN25TCG uses a PMOS pass transistor architecture enabling low dropout and fast transient response. Its internal error amplifier compares the regulated 2.5 V output against a precision voltage reference, while dedicated current-limit and thermal-shutdown circuits protect under fault conditions.
It supports active-high enable control (VTH,CE = 1.0 V turn-on, 0.4 V turn-off) and operates across 1.6–6.5 V input range. The device exhibits 45 µVRMS output noise (10 Hz–100 kHz) and maintains stable regulation with output capacitance as low as 2.2 µF ceramic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5 V ±1.0% (ensures stable core logic supply for 2.5 V I/O domains) |
| Max Output Current | 1 A continuous (supports high-current microcontrollers or sensors) |
| Dropout Voltage | 0.500 V typ at 1 A (enables operation down to 3.0 V input for 2.5 V output) |
| Quiescent Current | 65–90 µA (minimizes battery drain in always-on subsystems) |
| PSRR | 70 dB at 1 kHz (rejects switching noise from upstream DC-DC converters) |
| Thermal Shutdown | 165°C with 30°C hysteresis (prevents permanent damage during sustained overload) |
| Operating Temp | −40°C to +85°C ambient (suitable for industrial and consumer portable environments) |
Pinout & Package
Package: UDFN6 (1.8 mm × 2.0 mm, 0.5 mm pitch), exposed thermal pad (EP = GND), RoHS-compliant Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Vout | Dual parallel output pins reduce IR drop and improve current sharing for 1 A load |
| 3, EP | GND | Power ground return and primary thermal path via exposed pad |
| 4 | CE | Active-high enable; tie to Vin if unused; controls ultra-low standby current mode |
| 5, 6 | Vin | Dual parallel input pins lower series resistance and enhance decoupling effectiveness |
Key Features
| Feature | Design Value |
|---|---|
| Low Dropout Architecture | PMOS pass element enables 0.500 V dropout at full 1 A load, extending battery runtime |
| High Output Accuracy | ±1.0% over temperature ensures reliable logic-level compliance for 2.5 V interfaces |
| Ultra-Low Standby Current | 0.15–0.6 µA when CE = low, critical for long-term battery-backed operation |
| Integrated Protection | Current limit (250 mA short-circuit) and thermal shutdown prevent field failures |
| Ceramic Capacitor Compatible | Stable with ≥2.2 µF X5R/X7R ceramic output cap-no ESR requirements or tantalum dependency |
Applications
| Camcorders & Digital Cameras | Hand-Held Test Instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2502E/MB | 250 mA max output, 6 µA quiescent current, SOT-23-5 package | Limited to low-current peripherals; unsuitable for 1 A loads | Select only for ultra-low-IQ sub-100 mA rails where size and cost outweigh current capability |
| Torex XC6209F25MR-G | 1 A output, 1.0% accuracy, but 120 µA typical IQ and no enable pin | Lacks CE control; requires external logic for power sequencing or standby | Choose when enable functionality is unnecessary and slightly higher quiescent current is acceptable |

FAQ
What is the maximum input voltage rating for the NCP693HMN25TCG?
The NCP693HMN25TCG has an absolute maximum input voltage (VIN) rating of 7 V, with recommended operating range from 1.6 V to 6.5 V. Exceeding 7 V may cause permanent damage. For reliable 2.5 V output regulation, minimum input must be ≥3.0 V at full 1 A load due to dropout characteristics.
Does the NCP693HMN25TCG require an external capacitor on the CE pin?
No, the NCP693HMN25TCG does not require an external capacitor on the CE pin. The enable input is CMOS-compatible and internally buffered; it functions reliably with direct connection to a GPIO or pull-up to VIN. Adding capacitance may slow turn-on/turn-off timing and is not recommended unless intentional filtering is needed.
Can the NCP693HMN25TCG be used with a 1 µF ceramic output capacitor?
No-the NCP693HMN25TCG requires a minimum 2.2 µF ceramic output capacitor (X5R/X7R) for guaranteed stability across all operating conditions. Using 1 µF risks oscillation or degraded load transient response, as confirmed by the manufacturer's application circuit guidelines and stability analysis in the datasheet.
What is the thermal resistance (RJA) of the NCP693HMN25TCG in standard layout?
The NCP693HMN25TCG has a typical junction-to-ambient thermal resistance (RJA) of 114°C/W when mounted on an 80×80×1.5 mm FR4 PCB with 1 oz copper and 100 mm² copper pour under the exposed pad. This value assumes proper soldering of the EP pad and defines safe power dissipation limits under specified ambient conditions.
Is the NCP693HMN25TCG pin-compatible with other versions in the NCP693 family?
Yes-the NCP693HMN25TCG shares identical pinout, package (UDFN6, 1.8×2 mm), and footprint with all NCP693xMNxxTCG variants (e.g., NCP693HMN33TCG, NCP693DMN25TCG). Only the output voltage and enable behavior (H vs D version) differ; hardware layout is fully interchangeable across the series.
