Product details
Overview
NCP152MX300180TCG from onsemi is a dual-output, 150 mA low-dropout linear voltage regulator in XDFN6 (1.2 × 1.2 mm) package, delivering 3.0 V and 1.8 V outputs with ±2% accuracy, 150 mV typical dropout at full load, 50 µA typical quiescent current per channel, and 75 dB PSRR at 1 kHz - optimized for RF-sensitive battery-powered applications such as smartphones and wireless handsets.
For engineers reviewing the NCP152MX300180TCG datasheet, pinout, applications, or equivalent options, key selection considerations include independent enable control per channel, active output discharge, stability with 0.22 µF ceramic capacitors, thermal shutdown, and dual-channel current limiting - all critical for compact, low-noise portable power designs.
Technical Context
The NCP152MX300180TCG integrates two independent PMOS-based LDO regulators sharing a common input rail but featuring separate EN1/EN2 pins, dedicated output discharge paths, and individual current-limit and thermal-shutdown protection per channel. Its adaptive ground current architecture reduces IQ to ~50 µA per channel under light load while maintaining fast transient response.
Each regulator uses a bandgap reference and error amplifier to achieve ±2% output voltage accuracy over −40°C to +85°C, supports input voltages from 1.9 V to 5.25 V, and remains stable with minimal 0.22 µF X7R/X5R ceramic output capacitance - eliminating need for noise-bypass caps in RF sections.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.0 V (OUT1) and 1.8 V (OUT2), fixed, ±2% accuracy over temperature and load |
| Max Output Current | 150 mA per channel, with internal current limit protecting against overload and short-circuit |
| Dropout Voltage | 150 mV typical at 150 mA (for 3.0 V output), enabling operation from 3.15 V input |
| Quiescent Current | 50 µA typical per channel when enabled and unloaded; <1 µA total in shutdown |
| PSRR | 75 dB at 1 kHz, supporting clean power delivery to RF ICs and ADCs |
| Noise Performance | 75 µVRMS (10 Hz–100 kHz), no external bypass capacitor required |
| Enable Threshold | EN high = >0.9 V, EN low = <0.4 V; internal 300 nA pull-down ensures default-off state |
Pinout & Package
Package: XDFN6 (1.2 mm × 1.2 mm, 0.4 mm pitch), thermally enhanced with exposed pad tied to GND for improved heat dissipation (θJA = 170°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 3.0 V output | Requires 0.22 µF ceramic capacitor to GND for stability; supplies core logic or I/O rails |
| 2 - OUT2 | Regulated 1.8 V output | Requires 0.22 µF ceramic capacitor to GND; commonly powers memory or low-voltage peripherals |
| 3 - GND | Power ground reference | Must be soldered to PCB copper plane; shared return path for both regulators and thermal relief |
| 4 - EN2 | Enable control for OUT2 | Drives OUT2 ON/OFF; <0.4 V disables OUT2 and activates 50 Ω active discharge to GND |
| 5 - IN | Common input supply | Accepts 1.9–5.25 V; requires local 0.22 µF ceramic capacitor for noise filtering |
| 6 - EN1 | Enable control for OUT1 | Drives OUT1 ON/OFF independently; same threshold and discharge behavior as EN2 |
| EP - Exposed Pad | Thermal & electrical ground | Mandatory connection to GND plane for thermal performance and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | EN1 and EN2 allow sequenced or asynchronous power-up/down of 3.0 V and 1.8 V domains |
| Active output discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds upon disable - prevents floating or back-powering |
| Ultra-low-noise regulation | 75 µVRMS noise without external bypass cap - suitable for RF transceivers and precision analog circuits |
| Light-load efficiency | Adaptive ground current reduces IQ to ~50 µA per channel at light load - extends battery life in standby mode |
| Robust protection suite | Per-channel thermal shutdown (160°C), current limit (~280 mA), and short-circuit tolerance (indefinite duration) |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A202818PDBVR | 3.0 V/1.8 V outputs; 300 mA per channel; higher IQ (6.5 µA typ); smaller 1.0×1.0 mm DSBGA | Better suited for space-constrained, higher-current apps; lacks active discharge | Select if higher output current or smaller footprint is prioritized over discharge functionality |

FAQ
What are the exact output voltages of the NCP152MX300180TCG?
The NCP152MX300180TCG is factory-configured to deliver precisely 3.0 V on OUT1 and 1.8 V on OUT2, with ±2% output voltage accuracy across −40°C to +85°C junction temperature and full load range. These values are fixed and non-adjustable - confirmed in the Ordering Information table (page 17) of the official datasheet.
Does the NCP152MX300180TCG require external bypass capacitors for noise suppression?
No, the NCP152MX300180TCG achieves 75 µVRMS output noise (10 Hz–100 kHz) without any external noise-bypass capacitor. Its internal design and 0.22 µF ceramic output capacitors provide sufficient filtering for RF-sensitive applications - explicitly stated in the datasheet's Features and Applications Information sections.
How does the active discharge function work on the NCP152MX300180TCG?
When either EN1 or EN2 falls below 0.4 V, the corresponding output (OUT1 or OUT2) is disabled and its internal 50 Ω discharge transistor connects the output to GND. This rapidly discharges residual voltage - preventing back-powering, floating states, or latch-up in downstream circuitry. The feature is per-channel and verified in Figure 54 (Enable Turn-off) of the datasheet.
What is the minimum input voltage required for the NCP152MX300180TCG to regulate 3.0 V output?
To maintain regulation of the 3.0 V output at 150 mA, the NCP152MX300180TCG requires a minimum input voltage of 3.15 V - based on its typical 150 mV dropout voltage (VDO) at full load. At lighter loads, dropout drops further (e.g., 37 mV at 1 mA), allowing operation down to ~3.04 V.
Can the NCP152MX300180TCG operate with ceramic output capacitors smaller than 0.22 µF?
The NCP152MX300180TCG is guaranteed stable with ≥0.15 µF effective output capacitance - accounting for DC bias and temperature derating of small-case ceramics (e.g., 0201). While 0.22 µF is recommended, properly derated 0.15 µF X7R/X5R capacitors are acceptable, as confirmed in the Applications Information section (page 15) of the datasheet.
