Product details

Overview

NCP707BMX285TCG from onsemi is a 200 mA low-dropout linear regulator with fixed 2.85 V output, ultra-low 25 µA quiescent current, 22 µV_RMS output noise (100 Hz–100 kHz), and 114 mV typical dropout at 200 mA. It operates from 1.8 V to 5.5 V input and delivers ±2% output accuracy across load, line, and temperature for noise-sensitive portable power rails.

For engineers reviewing the NCP707BMX285TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN-4 1.0×1.0 mm package, EN-controlled enable/disable with 0.4 V/0.9 V thresholds, stable operation with 1 µF ceramic output capacitor, and thermal shutdown + current limit protection.

Technical Context

The NCP707BMX285TCG uses a PMOS pass transistor architecture enabling reverse-current blocking and very low dropout. Its adaptive ground current circuitry dynamically reduces IQ to 25 µA at no-load while maintaining regulation, critical for battery longevity in always-on subsystems.

Internal soft-start prevents output overshoot during turn-on, and the EN pin integrates hysteresis (56 mV) and deglitching to reject noise-induced toggling. Active discharge is absent in the 'B' variant-only present in A/C suffix versions-so the output floats high when disabled.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.85 V ±2% over −40°C to +125°C, load 0–200 mA, line VIN = VOUT+0.5 V to 5.5 V.
Dropout Voltage	114 mV typical at 200 mA - enables regulation from 2.964 V input, supporting single-cell Li-ion or 3.3 V rail post-LDO.
Quiescent Current	25 µA typical at no-load - extends battery life in standby mode for wearables and IoT sensors.
Output Noise	22 µV_RMS (100 Hz–100 kHz) - suitable for powering RF transceivers, ADC references, and audio codecs without added filtering.
PSRR	70 dB at 1 kHz - suppresses ripple from noisy switchers or shared power domains feeding mixed-signal SoCs.
Stability	Guaranteed with ≥1 µF ceramic output capacitor (X5R/X7R), ESR < 700 mΩ - eliminates need for tantalum or electrolytic caps.
Protection	Thermal shutdown (160°C), current limit (379 mA typ), and short-circuit safe - enables robust deployment in unattended edge devices.

Pinout & Package

XDFN-4 1.0 mm × 1.0 mm, 0.4 mm pitch, exposed pad (EPAD) for thermal dissipation. Package code: MX (Case 711AJ).

Pin/Terminal	Circuit Role	Design Meaning
1 - OUT	Regulated output voltage node	Connect ≥1 µF ceramic cap to GND; trace resistance must be minimized to preserve ±2% load regulation.
2 - GND	Power ground reference	Must connect EPAD directly to PCB ground plane for thermal performance (R_JA = 250°C/W).
3 - EN	Enable control input	Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables it; internal 180 nA pull-down ensures default-off state.
4 - IN	Input voltage supply	Accepts 1.8–5.5 V; requires ≥1 µF ceramic decoupling close to pin to suppress high-frequency noise and support transient response.

Key Features

Feature	Design Value
Ultra-low quiescent current	25 µA at zero load enables >1-year battery life in coin-cell-powered BLE sensors.
Low-noise regulation	22 µV_RMS noise floor avoids SNR degradation in precision analog front-ends and RF receivers.
Small-footprint stability	Stable with 1 µF ceramic output cap - reduces BOM count and PCB area vs. legacy LDOs requiring 10–22 µF.
Robust protection suite	Integrated thermal shutdown, current limit, and short-circuit protection eliminate need for external fault management circuitry.
EN-controlled sequencing	Dedicated enable pin with hysteresis and deglitching supports clean power-up/down sequencing in multi-rail systems.

FAQ

What is the maximum input voltage rating for the NCP707BMX285TCG?

The NCP707BMX285TCG has an absolute maximum input voltage rating of 6 V. Operation is specified over 1.8 V to 5.5 V, and exceeding 6 V risks permanent damage. For reliable long-term use, keep VIN ≤ 5.5 V under all conditions including transient spikes.

Does the NCP707BMX285TCG provide active output discharge when disabled?

No, the NCP707BMX285TCG does not include active output discharge. That feature is exclusive to the 'A' (R_DIS = 1.2 kΩ) and 'C' (R_DIS = 120 Ω) variants. When EN is pulled low, the NCP707BMX285TCG disconnects the pass transistor but leaves the output floating - external bleed resistors may be needed if rapid discharge is required.

Can the NCP707BMX285TCG operate stably with a 100 nF output capacitor?

Yes - the NCP707BMX285TCG is specified to remain stable with a minimum effective output capacitance of 100 nF. However, 1 µF is recommended to ensure margin against capacitance loss due to DC bias, temperature, and tolerance; 100 nF may reduce transient response and PSRR at high frequencies.

What is the typical enable turn-on time for the NCP707BMX285TCG?

The typical enable turn-on time for the NCP707BMX285TCG is 200 µs - defined as the time from EN rising above 0.9 V to VOUT reaching 98% of 2.85 V with C_OUT = 1 µF. This value is consistent across temperature and load conditions per the datasheet's Electrical Characteristics table.

How does the NCP707BMX285TCG handle reverse current flow from VOUT to VIN?

The NCP707BMX285TCG uses a PMOS pass transistor with an inherent body diode that conducts if VOUT exceeds VIN. Under such reverse-bias conditions, uncontrolled current can flow. The datasheet recommends external protection (e.g., a series Schottky diode) if VOUT > VIN is possible in the system design.
