onsemi NCP693HMN10TCG

Overview

NCP693HMN10TCG from onsemi is a 1.0 V fixed-output, 1 A CMOS low-dropout linear regulator in a 6-pin DFN 1.8×2 mm package, featuring ±1.0% output voltage accuracy, ultra-low 65–90 µA quiescent current, and chip enable (CE) for standby mode - used to power core logic in portable battery-powered instrumentation.

For engineers reviewing the NCP693HMN10TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 1 A (0.45–1.45 V), thermal shutdown at 165°C, PSRR of 70 dB at 1 kHz, and compatibility with ceramic or tantalum output capacitors ≥2.2 µF.

Technical Context

The NCP693HMN10TCG integrates a PMOS pass transistor, precision voltage reference, error amplifier, and current-limit/thermal-shutdown protection. Its CE input enables logic-controlled shutdown with 0.4 V (low) / 1.0 V (high) thresholds, delivering standby current as low as 0.15–0.6 µA.

Designed for high-current portable systems, it operates across −40°C to +85°C ambient, supports input voltages from 1.6 V to 6.5 V, and maintains regulation down to 0.13 V dropout at 300 mA (1.0 V output), with output noise of 45 µV_RMS (10 Hz–100 kHz).

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage rating for the NCP693HMN10TCG?

The NCP693HMN10TCG 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. The device is optimized for single-cell Li-ion (up to 4.2 V) or dual-cell alkaline (up to 3.2 V) inputs, and its 6.5 V upper limit accommodates transient spikes in portable systems. Always maintain input within this range to ensure reliability and avoid overstress.

Does the NCP693HMN10TCG require an external capacitor on the CE pin?

No, the NCP693HMN10TCG 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 microcontroller GPIO or pull-up resistor to Vin. Adding capacitance may slow turn-on/turn-off timing and is unnecessary per the datasheet. For noise immunity in electrically noisy environments, a small RC filter (e.g., 10 kΩ + 100 pF) can be added, but it is not mandatory for basic operation of the NCP693HMN10TCG.

Can the NCP693HMN10TCG be used with a 2.2 µF ceramic output capacitor?

Yes, the NCP693HMN10TCG is explicitly characterized and stable with a 2.2 µF ceramic output capacitor, as confirmed in the datasheet's Application Information section and Figure 2. Ceramic capacitors with X5R or X7R dielectric and ≤100 mΩ ESR are recommended. Larger values (e.g., 4.7–10 µF) further improve load transient response and PSRR, but 2.2 µF meets minimum stability requirements and is sufficient for most portable applications using the NCP693HMN10TCG.

What is the thermal shutdown behavior of the NCP693HMN10TCG?

The NCP693HMN10TCG activates thermal shutdown at 165°C junction temperature and remains latched off until junction temperature falls by 30°C (to ~135°C), providing hysteresis to prevent oscillation. During shutdown, output is disabled and quiescent current drops to standby levels. Recovery is automatic upon cooling - no external reset is needed. This protects the NCP693HMN10TCG and downstream circuitry during sustained overload or inadequate PCB heatsinking.

Is the NCP693HMN10TCG pin-compatible with other versions in the NCP693 family?

Yes, all NCP693 variants - including NCP693HMN08TCG (0.8 V), NCP693HMN12TCG (1.2 V), and NCP693DMNxxTCG (D-version with auto-discharge) - share identical UDFN6 (1.8×2 mm) pinout and footprint. The NCP693HMN10TCG uses pins 1–2 (Vout), 3 & EP (GND), 4 (CE), and 5–6 (Vin); this mapping is consistent across the series. However, functional differences (e.g., auto-discharge in D-version) mean electrical compatibility requires verification per application - the NCP693HMN10TCG itself does not include auto-discharge.
