Product details
Overview
NCP707BMX300TCG from onsemi is a 200 mA low-dropout (LDO) voltage regulator with fixed 3.0 V output, optimized for battery-powered portable electronics. It delivers ±2% output accuracy across load, line, and temperature, achieves 111 mV typical dropout at 200 mA, and maintains ultra-low 25 µA quiescent current at no-load - enabling multi-week standby in wearables and IoT sensors.
For engineers reviewing the NCP707BMX300TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.8–5.5 V input range, 22 µVRMS output noise (100 Hz–100 kHz), 70 dB PSRR at 1 kHz, stability with 1 µF ceramic output capacitor, and XDFN 1.0 × 1.0 mm package for space-constrained PCB layouts.
Technical Context
The NCP707BMX300TCG uses a PMOS pass transistor architecture enabling true reverse-current blocking and low dropout performance. Its adaptive ground current circuitry dynamically reduces IQ to 25 µA at zero load while scaling to 240 µA at full 200 mA output - critical for energy harvesting and coin-cell applications.
Internal protection includes thermal shutdown (160°C trip, 20°C hysteresis), current limiting (379 mA typ.), and EN-controlled active discharge only in A/C variants - the B variant lacks active discharge, confirmed by onsemi ordering table and block diagram footnote.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C, load 0–200 mA, line 3.5–5.5 V - ensures stable MCU core rail without external feedback. |
| Dropout Voltage | 111 mV typical at 200 mA - enables operation from single Li-ion (3.0 V min) or two alkaline cells (3.0 V fresh). |
| Quiescent Current | 25 µA typical at no-load - extends battery life in always-on sensor nodes beyond 1 year on CR2032. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - suitable for RF transceivers and precision ADC reference supplies. |
| PSRR | 70 dB at 1 kHz - suppresses switching regulator ripple from upstream DC/DC converters. |
| Stability | Guaranteed with ≥1 µF ceramic COUT (X5R/X7R), ESR < 700 mΩ - eliminates need for tantalum or polymer capacitors. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V and 3.3 V GPIO without level-shifting. |
Pinout & Package
XDFN-4 1.0 mm × 1.0 mm, 0.4 mm pitch, exposed thermal pad (EPAD). RoHS-compliant, halogen-free, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers 3.0 V to load; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 - GND | Power ground | Reference for all internal circuits; EPAD must be soldered directly to PCB ground plane for thermal management. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and reduces IN current to 0.01 µA - no active discharge in B variant. |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor to GND near pin to suppress high-frequency noise and support load transients. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ with dynamic adjustment | 25 µA at 0 mA → 240 µA at 200 mA - minimizes battery drain during sleep/wake cycles without sacrificing full-load performance. |
| Low-noise regulated output | 22 µVRMS noise floor - preserves signal integrity in audio codecs, BLE radios, and medical front-ends. |
| High PSRR at 1 kHz | 70 dB rejection of DC/DC switching noise - enables clean LDO rails downstream of noisy buck converters. |
| Robust protection suite | Thermal shutdown (160°C), current limit (379 mA), and short-circuit immunity - eliminates need for external fault management. |
| Minimal external components | Stable with 1 µF ceramic CIN/COUT - reduces BOM count, PCB area, and cost vs. legacy LDOs requiring 10+ µF capacitors. |

FAQ
What is the maximum input voltage rating for the NCP707BMX300TCG?
The NCP707BMX300TCG has an absolute maximum input voltage of 6 V, but its recommended operating range is 1.8 V to 5.5 V. Exceeding 5.5 V may trigger internal protection or degrade reliability. The device maintains regulation down to 1.8 V input - critical for brown-out operation with depleting batteries.
Does the NCP707BMX300TCG include active output discharge?
No, the NCP707BMX300TCG does not include active output discharge. Only A- and C-suffix variants (e.g., NCP707AMX300TCG) feature this function. The B-suffix denotes standard enable/disable operation without pull-down on shutdown - verified in onsemi's ordering table and block diagram footnote.
Can the NCP707BMX300TCG operate stably with a 100 nF output capacitor?
Yes, the NCP707BMX300TCG remains stable with a minimum 100 nF ceramic output capacitor, though 1 µF is recommended for full transient performance and safety margin against capacitance loss due to DC bias and temperature. Stability is independent of ESR, supporting modern low-ESR MLCCs.
What is the thermal resistance (θJA) of the NCP707BMX300TCG in typical PCB layout?
The NCP707BMX300TCG has a typical θJA of 250°C/W on a 2 oz FR4 PCB with 100 mm² copper area. With enhanced thermal pads and multiple vias to inner ground planes, θJA can improve to ~120°C/W - enabling continuous 200 mA operation at ambient temperatures up to +70°C.
How does the EN pin behavior differ between NCP707BMX300TCG and A/C variants?
The EN pin functions identically across all NCP707 variants: 0.4 V threshold for disable, 0.9 V for enable, with 56 mV hysteresis. However, only A/C variants activate the output discharge transistor upon disable. The NCP707BMX300TCG holds VOUT floating after disable - requiring external bleed resistors if rapid discharge is needed.
