Product details
Overview
NCP154MX100180TAG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent input pins (IN1/IN2), delivering 1.0 V and 1.8 V outputs. It features ultra-low noise (75 µVrms, 10 Hz–100 kHz), high PSRR (75 dB at 1 kHz), and adaptive ground current for battery-powered RF-sensitive applications such as smartphone baseband and RF front-end power domains.
For engineers reviewing the NCP154MX100180TAG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel independent enable control, 140 mV typical dropout at 300 mA (for 3.3 V output), active output discharge, thermal shutdown, and stable operation with only 1 µF ceramic output capacitors per channel.
Technical Context
The NCP154MX100180TAG integrates two independent PMOS-based LDO regulators sharing a common ground but with separate input, enable, and output terminals. Each channel employs bandgap-referenced error amplifiers, current-limit protection, and thermal shutdown circuitry-operating autonomously without cross-channel interference.
Its adaptive ground current feature reduces quiescent current to 55 µA per channel under light load, while the active discharge path (50 Ω) ensures rapid turn-off of each output when its EN pin falls below 0.4 V-critical for sequencing and power-domain isolation in multi-rail portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.0 V (OUT1) and 1.8 V (OUT2); fixed, factory-trimmed; ±2% accuracy for VOUT > 2 V, ±60 mV for VOUT ≤ 2 V |
| Max Output Current | 300 mA per channel; current limit set to 400 mA typ. to sustain short-circuit protection without latch-up |
| Dropout Voltage | 140 mV typical at 300 mA for 3.3 V output; actual dropout varies by VOUT (e.g., 360 mV at 1.5 V output) |
| PSRR | 75 dB at 1 kHz; enables clean power delivery to noise-sensitive RF ICs without external bypass capacitors |
| Quiescent Current | 55 µA per channel (typ.) at no load; drops to 110 µA total when both channels enabled, optimizing battery runtime |
| Noise Performance | 75 µVrms (10 Hz–100 kHz); eliminates need for dedicated noise-filtering capacitors in compact layouts |
| Enable Threshold | EN high threshold = 0.9 V (min), low threshold = 0.4 V (max); supports direct GPIO control from 1.8 V/3.3 V logic |
Pinout & Package
Package: XDFN-8, 1.2 mm × 1.6 mm, 0.4 mm pitch, exposed thermal pad (EP) requiring solder connection to GND plane for thermal dissipation (θJA = 160°C/W on 1 oz FR4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, EP | GND / Exposed Pad | Power ground return and primary thermal path; EP must be soldered to PCB GND copper for safe operation at full load |
| 2 | OUT1 | Regulated 1.0 V output; requires 1 µF X5R/X7R ceramic capacitor to GND for stability |
| 3 | OUT2 | Regulated 1.8 V output; independently stabilized with its own 1 µF output capacitor |
| 5 | EN2 | Enable control for OUT2; <0.4 V disables OUT2 and activates 50 Ω active discharge to GND |
| 6 | IN2 | Input supply for OUT2 channel; decoupling capacitor required close to pin |
| 7 | IN1 | Input supply for OUT1 channel; electrically isolated from IN2 for dual-input flexibility |
| 8 | EN1 | Enable control for OUT1; identical logic thresholds and discharge behavior as EN2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | Enables separate power sourcing (e.g., battery + USB) or rail isolation for fault containment |
| Active output discharge | 50 Ω internal pull-down per output ensures fast, controlled turn-off (<1 ms decay) without external components |
| Stable with 1 µF ceramic COUT | Eliminates need for larger or higher-ESR capacitors-reducing BOM count and board area in space-constrained designs |
| Thermal shutdown & current limit | Independent per-channel protection: 160°C trip, 20°C hysteresis; prevents damage during sustained overload or poor heatsinking |
| Ultra-low noise, no bypass cap needed | 75 µVrms output noise allows direct powering of PLLs, ADCs, and RF synthesizers without added filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D101GR-G | Single-output, 1.0 V only; no second channel or independent EN; 200 mA max; 65 dB PSRR at 1 kHz | Cannot replace dual-rail functionality; suitable only if 1.8 V rail is sourced elsewhere | Select only when system requires only one regulated rail and space constraints favor smaller SOT-25 package |
| Richtek RT9080L-180100GJ6F | Dual-output (1.8 V/1.0 V), same XDFN-8 package; 300 mA per channel; 70 dB PSRR at 1 kHz; 90 µVrms noise | Higher noise and lower PSRR than NCP154MX100180TAG; lacks active discharge on EN disable | Acceptable for cost-sensitive designs where ultra-low noise and fast turn-off are non-critical |

FAQ
What output voltages does the NCP154MX100180TAG provide?
The NCP154MX100180TAG provides fixed, factory-trimmed output voltages of 1.0 V on OUT1 and 1.8 V on OUT2. These values are specified in the Ordering Information table (Table 5) and confirmed across electrical characteristics testing. Output accuracy is ±60 mV for the 1.0 V rail and ±2% for the 1.8 V rail over −40°C to +85°C junction temperature.
Does the NCP154MX100180TAG require external capacitors for stability?
Yes-the NCP154MX100180TAG requires a minimum 1 µF X5R or X7R ceramic capacitor from each output (OUT1 and OUT2) to GND, placed as close as possible to the respective pins. Input capacitors (1 µF ceramic per IN1/IN2) are also recommended. The device is explicitly characterized and guaranteed stable with this configuration; no additional ESR or capacitance is needed.
How does the enable function work on the NCP154MX100180TAG?
The NCP154MX100180TAG has two independent enable pins: EN1 controls OUT1 and EN2 controls OUT2. Driving either EN pin above 0.9 V (min) enables its corresponding output; driving it below 0.4 V (max) disables the output and activates an internal 50 Ω active discharge path to GND. Each EN pin includes a 300 nA internal pull-down, ensuring default disable when left floating.
What thermal protection features does the NCP154MX100180TAG include?
The NCP154MX100180TAG incorporates per-channel thermal shutdown with a typical trip point of 160°C and 20°C hysteresis. When die temperature exceeds this threshold, the affected channel shuts down while the other remains operational. Recovery occurs automatically once junction temperature falls below 140°C. This design prevents catastrophic failure during overload or insufficient PCB copper area.
Can the NCP154MX100180TAG be used with input voltages below 2.0 V?
Yes-the NCP154MX100180TAG operates across an input voltage range of 1.9 V to 5.25 V per channel. At VIN = 1.9 V, it can still regulate 1.0 V and 1.8 V outputs, though dropout margin shrinks (e.g., 1.0 V output requires ≥1.14 V input for 140 mV dropout headroom). Full specifications-including PSRR, noise, and load regulation-are guaranteed within this range.
