Product details
Overview
NCP707BMX180TCG from onsemi is a 200 mA low-dropout (LDO) voltage regulator with fixed 1.8 V output, optimized for battery-powered portable electronics. It delivers ±2% output accuracy over load/line/temperature, achieves 100 mV typical dropout at 200 mA, and maintains ultra-low 25 µA quiescent current at no-load-enabling extended runtime in space-constrained, noise-sensitive applications such as GPS modules and Bluetooth handsets.
For engineers reviewing the NCP707BMX180TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.8 V fixed output, XDFN 1.0×1.0 mm package, 22 µVRMS output noise (100 Hz–100 kHz), 70 dB PSRR at 1 kHz, and EN-controlled shutdown with <1 µA disable current.
Technical Context
The NCP707BMX180TCG employs a PMOS pass transistor architecture enabling reverse-current blocking and eliminating external body-diode concerns. Its adaptive ground current circuitry dynamically reduces IQ to 25 µA at zero load while maintaining regulation, and internal soft-start prevents output overshoot during enable transitions.
It integrates thermal shutdown (160°C trip, 20°C hysteresis) and foldback current limiting (379 mA typ. current limit, 390 mA short-circuit limit), and operates stably with only a 1 µF ceramic output capacitor-no ESR requirement-making it compatible with modern low-ESR MLCCs in 0402 footprints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% over −40°C to +125°C, load 0–200 mA, line VIN = 2.3 V to 5.5 V. |
| Dropout Voltage | 100 mV typical at 200 mA (VIN ≥ 1.9 V), enabling operation from single-cell Li-ion or 2-cell alkaline sources. |
| Quiescent Current | 25 µA typical at no-load; rises to 240 µA at 200 mA load-critical for always-on sensor nodes. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz), suitable for RF power supply filtering in Bluetooth/Wi-Fi ICs. |
| PSRR | 70 dB at 1 kHz, 58 dB at 100 Hz-suppresses switching noise from upstream DC-DC converters. |
| Enable Threshold | EN high threshold = 0.9 V, low threshold = 0.4 V; built-in 56 mV hysteresis prevents noise-induced toggling. |
| Stability | Stable with ≥1 µF ceramic output capacitor; max ESR ≤ 700 mΩ-no tantalum required. |
Pinout & Package
Package: XDFN-4 (1.0 mm × 1.0 mm, 0.4 mm height), case 711AJ, exposed pad (EPAD) for thermal dissipation. RoHS-compliant, Pb-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 1.8 V; requires ≥1 µF ceramic capacitor to GND for stability; trace resistance must be minimized for ±2% accuracy. |
| 2 - GND | Power ground | Reference return for IN, OUT, and EN; EPAD must be soldered directly to PCB ground plane for thermal performance. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables output and reduces IN current to <1 µA. |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress high-frequency noise and support transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 25 µA no-load quiescent current extends battery life in always-on IoT sensors and wearables. |
| Low-noise regulation | 22 µVRMS output noise ensures clean power for RF transceivers and precision analog circuits. |
| Small-footprint stability | Stable with 1 µF ceramic output capacitor-enables use of 0402-size MLCCs, reducing board area by >50% vs. legacy LDOs. |
| Robust protection | Integrated thermal shutdown (160°C), current limit (379 mA), and short-circuit immunity prevent field failures in unattended devices. |
| EN-controlled shutdown | EN pin draws only 180 nA typical; internal pull-down ensures safe default-OFF state when left floating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 250 mA rated, 1.8 V fixed, 1.6 µA IQ, but higher 170 mV dropout at 250 mA and no EN pin. | Lacks enable control and has lower PSRR (60 dB @ 1 kHz); unsuitable for dynamic power-gating systems. | Select when ultra-low IQ dominates over EN functionality and dropout margin is sufficient. |
| Torex XC6210B182MR-G | 200 mA rated, 1.8 V fixed, 35 µA IQ, 120 mV dropout, EN pin, but requires ≥2.2 µF output capacitance for stability. | Higher minimum COUT increases solution size and cost; less optimal for space-constrained designs using 1 µF MLCCs. | Select when broader input range (1.5–6.0 V) is needed and board area permits larger output capacitor. |
Compared with MCP1700T-1802E/TT and XC6210B182MR-G, the NCP707BMX180TCG uniquely balances 25 µA IQ, 100 mV dropout, EN control, and 1 µF stability in a 1.0×1.0 mm footprint-making it optimal for miniaturized, battery-gated, noise-sensitive portable systems.

FAQ
What is the maximum input voltage rating for the NCP707BMX180TCG?
The NCP707BMX180TCG has an absolute maximum input voltage of 6 V. Operation is specified from 1.8 V to 5.5 V; exceeding 6 V risks permanent damage. For reliable long-term use, maintain VIN ≤ 5.5 V under all conditions including ripple and transients.
Does the NCP707BMX180TCG include active output discharge?
No, the NCP707BMX180TCG does not include active output discharge. Only versions with "A" or "C" suffixes (e.g., NCP707AMX180TCG) feature this function. The "B" suffix indicates standard enable/disable operation without output pull-down on shutdown.
Can the NCP707BMX180TCG operate with a 100 nF output capacitor?
Yes-the NCP707BMX180TCG remains stable with a minimum 100 nF ceramic output capacitor. However, the datasheet specifies 1 µF as the recommended value to ensure adequate phase margin across temperature, voltage, and manufacturing variation; 100 nF may reduce transient response margin.
What is the thermal resistance (θJA) of the NCP707BMX180TCG in typical layout?
In a standard 2 oz copper PCB with 100 mm² ground plane connected to the EPAD, the NCP707BMX180TCG exhibits θJA ≈ 250°C/W. With enhanced thermal layout (e.g., 4-layer board, multiple vias to inner ground planes), θJA can improve to ~120°C/W, enabling full 200 mA load at +85°C ambient.
Is the NCP707BMX180TCG compatible with ceramic capacitors having X5R dielectric?
Yes-the NCP707BMX180TCG is fully compatible with X5R ceramic capacitors for both input (CIN) and output (COUT). X5R offers stable capacitance over temperature and voltage, low ESR, and is explicitly recommended in the datasheet for optimal transient response and PSRR performance.
