Product details
Overview
NCP152MX280180TCG from onsemi is a dual-output, 150 mA low-dropout linear voltage regulator with independent 2.8 V and 1.8 V outputs, 150 mV typical dropout at full load, 50 µA typical quiescent current per channel, and 75 dB PSRR at 1 kHz-designed for RF-sensitive battery-powered applications such as smartphone baseband and RF front-end power domains.
For engineers reviewing the NCP152MX280180TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, active output discharge, stability with 0.22 µF ceramic capacitors, and thermal shutdown with hysteresis-critical for compact portable designs requiring low-noise, low-IQ power management.
Technical Context
The NCP152MX280180TCG integrates two independent PMOS-based LDO regulators sharing a common input but featuring separate EN1/EN2 control and dedicated OUT1/OUT2 pins. Each channel employs adaptive ground current logic to reduce IQ under light load while maintaining regulation accuracy within ±2% over −40°C to +85°C.
Its internal bandgap reference feeds dual error amplifiers driving PMOS pass transistors with integrated current limiting (280 mA typ.) and thermal shutdown (160°C trip, 20°C hysteresis). The active discharge circuit-enabled when EN < 0.4 V-pulls each output to GND via a 50 Ω internal resistor for fast turn-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 2.8 V (OUT1) and 1.8 V (OUT2), fixed and non-adjustable-enables direct powering of core logic and I/O rails without external feedback networks. |
| Max Output Current | 150 mA per channel-supports moderate-power digital subsystems like application processors, memory interfaces, and wireless co-processors. |
| Dropout Voltage | 160 mV typical at 150 mA for VOUT = 2.8 V-allows operation from 3.0 V input while sustaining full load, critical for Li-ion battery discharge curves. |
| Quiescent Current | 50 µA typical per enabled channel-minimizes standby power loss in always-on subsystems such as Bluetooth LE or sensor hubs. |
| PSRR | 75 dB at 1 kHz-suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in RF receivers and ADC references. |
| Output Noise | 75 µVRMS (10 Hz–100 kHz)-eliminates need for external noise-bypass capacitors, reducing BOM count and PCB area in space-constrained layouts. |
| Enable Threshold | VEN_H = 0.9 V, VEN_L = 0.4 V-ensures robust logic-level compatibility with 1.8 V and 3.3 V GPIOs without level-shifting. |
Pinout & Package
Package: XDFN6 1.2 mm × 1.2 mm, 0.4 mm pitch, exposed thermal pad (Case 711AT). Requires soldering exposed pad to GND plane for thermal performance (θJA = 170°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 2.8 V output | Connects to 0.22 µF ceramic capacitor to GND; supplies power to 2.8 V domain (e.g., RF transceiver I/O). |
| 2 - OUT2 | Regulated 1.8 V output | Connects to 0.22 µF ceramic capacitor to GND; powers 1.8 V core logic (e.g., application processor cores). |
| 3 - GND | Power ground reference | Common return path for both channels; must be tied to PCB ground plane and exposed pad for thermal dissipation. |
| 4 - EN2 | Enable control for OUT2 | Drives >0.9 V to enable 1.8 V output; <0.4 V disables OUT2 and activates 50 Ω active discharge to GND. |
| 5 - IN | Shared input supply | Accepts 1.9–5.25 V; requires 0.22 µF ceramic capacitor close to pin to suppress high-frequency noise and transient spikes. |
| 6 - EN1 | Enable control for OUT1 | Drives >0.9 V to enable 2.8 V output; <0.4 V disables OUT1 and activates independent 50 Ω active discharge. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Ground Current | Reduces IQ to ~50 µA per channel at light load while maintaining regulation-extends battery life in sleep modes without sacrificing wake-up response. |
| Active Output Discharge | 50 Ω internal discharge path per output ensures VOUT falls rapidly (<10 µs) when disabled-prevents floating voltages that could cause latch-up in downstream logic. |
| Stability with Small Capacitors | Guaranteed stable with 0.22 µF X7R/X5R ceramic output caps-enables use of 0402/0201 footprints, saving >0.5 mm² PCB area per channel vs. legacy LDOs requiring ≥2.2 µF. |
| Independent Dual Enable | Separate EN1 and EN2 pins allow sequencing (e.g., power 1.8 V core before 2.8 V I/O) or independent shutdown-essential for power-domain isolation in multi-rail SoC systems. |
| Robust Protection | Per-channel thermal shutdown (160°C), current limit (280 mA typ.), and short-circuit tolerance (indefinite duration)-ensures fault containment without affecting the healthy channel. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6223D2818MR-G | Fixed 2.8 V / 1.8 V outputs; 100 mA per channel; 25 µA IQ; SOT-26 package (larger footprint) | Limited to 100 mA-insufficient for 150 mA RF transceiver loads; lacks active discharge | Select only if lower IQ and smaller solution height outweigh current capability and discharge requirements. |

FAQ
What are the exact output voltages of the NCP152MX280180TCG?
The NCP152MX280180TCG delivers fixed 2.8 V on OUT1 and 1.8 V on OUT2, as confirmed by the ordering information table in the official onsemi datasheet (Rev. 6, October 2022). These values are factory-trimmed and do not require external resistive feedback-ensuring ±2% accuracy over temperature and load.
Does the NCP152MX280180TCG require external bypass capacitors for noise suppression?
No-the NCP152MX280180TCG achieves 75 µVRMS output noise (10 Hz–100 kHz) without external noise-bypass capacitors, as verified in the datasheet's Electrical Characteristics and Typical Characteristics sections (Figures 27–30). Its internal architecture eliminates the need for additional 10 nF–100 nF ceramic caps typically used with legacy LDOs.
How does the active discharge feature work on the NCP152MX280180TCG?
When either EN1 or EN2 falls below 0.4 V, the corresponding output (OUT1 or OUT2) is actively pulled to GND through an internal 50 Ω resistor, as documented in the Pin Function Description and Applications Information sections. This ensures rapid, controlled discharge-critical for preventing back-powering and ensuring clean power-down sequencing in multi-rail systems.
What is the minimum output capacitance required for stability with the NCP152MX280180TCG?
The NCP152MX280180TCG is stable with a minimum 0.22 µF X7R or X5R ceramic capacitor per output, as stated in the Features list and Applications Information section. The device remains stable down to 0.15 µF effective capacitance to accommodate DC bias and temperature derating-enabling reliable use of small 0201/0402 packages.
Can the NCP152MX280180TCG operate from a 3.0 V input while delivering full 150 mA at 2.8 V?
Yes-the NCP152MX280180TCG has a typical dropout voltage of 160 mV at 150 mA for the 2.8 V output, as shown in Table 1 (ELECTRICAL CHARACTERISTICS) and Figure 13. With a 3.0 V input, it sustains full 150 mA load on OUT1 while maintaining regulation, making it compatible with the declining voltage profile of single-cell Li-ion batteries.
