Product details
Overview
NCP154MX300300TAG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent IN1/IN2 inputs and fixed 3.0 V / 3.0 V outputs. It delivers ultra-low noise (75 µVrms), high PSRR (75 dB at 1 kHz), and very low dropout (150 mV typical at 300 mA) - optimized for RF-sensitive battery-powered applications such as smartphones and wireless handsets.
For engineers reviewing the NCP154MX300300TAG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, adaptive ground current for light-load efficiency, active output discharge, thermal shutdown, and stability with only 1 µF ceramic output capacitors.
Technical Context
The NCP154MX300300TAG integrates two independent PMOS LDO regulators sharing a common ground but with separate input, enable, and output terminals. Each channel features dedicated EN1/EN2 logic with 0.4 V low-threshold and 0.9 V high-threshold, enabling precise sequencing and fast turn-off via 50 Ω active discharge.
Its architecture supports simultaneous or staggered regulation of two 3.0 V rails under varying load conditions (1 mA to 300 mA per channel), with built-in current limiting (400 mA typ.), thermal shutdown (160 °C), and reverse-current protection - all within a thermally enhanced XDFN8 1.2 × 1.6 mm package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V / 3.0 V - eliminates external feedback resistors; ensures matched rail generation for dual-core processors or I/O + core supplies. |
| Max Output Current | 300 mA per channel - supports moderate-power RF transceivers, sensor hubs, or memory interfaces without derating. |
| Dropout Voltage | 150 mV typical at 300 mA - enables operation down to VIN = 3.15 V, extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 55 µA per channel - reduces standby power loss in always-on subsystems like Bluetooth® or ZigBee® radios. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters, critical for analog/RF signal integrity. |
| Noise (10–100 kHz) | 75 µVrms - meets stringent noise requirements for ADC references, PLLs, and audio codecs without added bypass caps. |
| Stability | Guaranteed with ≥1 µF X5R/X7R ceramic output capacitor - simplifies layout and lowers BOM cost vs. traditional LDOs requiring larger or specialized caps. |
Pinout & Package
Package: XDFN8 1.2 × 1.6 mm (Case 711AS), thermally enhanced with exposed pad tied to GND for efficient heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, EP | GND | Power ground pins and exposed pad - must be soldered to large copper plane for thermal management and low-impedance return path. |
| 2 | OUT1 | Regulated 3.0 V output for Channel 1 - requires local 1 µF ceramic capacitor to GND for stability and transient response. |
| 3 | OUT2 | Regulated 3.0 V output for Channel 2 - independently regulated; decoupled with its own 1 µF ceramic capacitor. |
| 5 | EN2 | Enable input for Channel 2 - <0.4 V disables OUT2 and activates 50 Ω discharge; >0.9 V enables regulation. |
| 6 | IN2 | Input supply for Channel 2 - accepts 1.9–5.25 V; requires local 1 µF ceramic capacitor for noise filtering. |
| 7 | IN1 | Input supply for Channel 1 - electrically isolated from IN2; enables dual-rail flexibility (e.g., separate battery/DC-DC sources). |
| 8 | EN1 | Enable input for Channel 1 - independent control allows power sequencing, dynamic rail shutdown, or fault isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Ground Current | Reduces IQ to 55 µA per channel at light load - extends battery life in sleep modes without sacrificing startup speed. |
| Active Output Discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND in <1 ms when disabled - prevents floating voltages and ensures clean power-down sequencing. |
| Dual Independent Inputs | IN1 and IN2 accept separate supplies - supports mixed-source designs (e.g., battery + USB, or primary + backup rail). |
| Thermal Shutdown & Current Limit | Independent per-channel protection - one shorted output does not affect regulation on the other channel. |
| Pb-Free XDFN8 Package | 1.2 × 1.6 mm footprint with 0.4 mm pitch - enables ultra-compact layouts in space-constrained mobile and wearable devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2023DQNR | Single-output 3.0 V LDO (300 mA), no dual-channel capability; lower IQ (6.5 µA) but no independent inputs or active discharge. | Requires two devices for dual-rail use; lacks per-channel enable and discharge - unsuitable for sequencing-critical designs. | Select only if dual-channel integration is unnecessary and ultra-low IQ dominates design priority. |
| RT9080L-3030GJ6F | Dual 3.0 V/3.0 V LDO (300 mA/ch), similar XDFN package, but higher dropout (220 mV) and lower PSRR (65 dB @ 1 kHz). | Marginally acceptable for non-RF applications; insufficient PSRR headroom for cellular/Wi-Fi coexistence. | Consider only in cost-sensitive, non-RF applications where 10 dB PSRR margin is acceptable. |
Compared with TPS7A2023DQNR and RT9080L-3030GJ6F, the NCP154MX300300TAG uniquely combines dual independent inputs, per-channel enable/discharge, 75 dB PSRR, and 150 mV dropout - making it the only option that satisfies concurrent RF noise immunity, power sequencing, and space-constrained dual-rail requirements.

FAQ
What output voltages does the NCP154MX300300TAG provide?
The NCP154MX300300TAG provides two fixed, independent 3.0 V outputs - OUT1 and OUT2 - as indicated by the "300300" suffix in the part number. These are factory-trimmed and do not require external feedback components, ensuring tight accuracy (±2% for VOUT > 2 V) across −40°C to +85°C operating temperature.
Does the NCP154MX300300TAG require external capacitors for stability?
Yes, the NCP154MX300300TAG requires a minimum 1 µF X5R or X7R ceramic capacitor on each output (OUT1 and OUT2) placed as close as possible to the respective pins. It is also recommended to place a 1 µF ceramic capacitor on each input (IN1 and IN2). The device is designed to remain stable with these values and does not require ESR tuning or additional compensation networks.
How does the enable functionality work on the NCP154MX300300TAG?
The NCP154MX300300TAG features independent enable inputs: EN1 controls OUT1 and EN2 controls OUT2. Driving EN1 or EN2 above 0.9 V enables the corresponding output; driving below 0.4 V disables it and activates the 50 Ω active discharge path to pull the output to GND. Each EN pin has an internal 300 nA pull-down, ensuring safe default-off behavior when left unconnected.
What thermal protection features does the NCP154MX300300TAG include?
The NCP154MX300300TAG incorporates per-channel thermal shutdown with a typical trip point of 160°C and hysteresis of 20°C (reset at ~140°C). This protection operates independently per channel - a thermal fault on OUT1 does not disable OUT2. The XDFN8 package's exposed pad must be soldered to a GND copper plane to maintain junction-to-ambient thermal resistance (θJA = 160°C/W on 1 oz FR4).
Can the NCP154MX300300TAG be used with input voltages below 3.0 V?
Yes, the NCP154MX300300TAG supports input voltages from 1.9 V to 5.25 V per channel. With a 3.0 V output and typical dropout of 150 mV, it can regulate down to VIN = 3.15 V at full 300 mA load. At lighter loads, dropout decreases further - enabling operation from a partially discharged single-cell Li-ion battery (e.g., 3.2 V) while maintaining regulation on both 3.0 V rails.
