Product details
Overview
NCP152MX300280TCG from onsemi is a dual-output, low-noise, low-quiescent-current linear voltage regulator delivering 150 mA per channel with independent 3.0 V and 2.8 V outputs. It features 150 mV typical dropout at 150 mA, 75 dB PSRR at 1 kHz, and stable operation with only 0.22 µF ceramic output capacitors - making it ideal for RF-sensitive battery-powered applications such as wireless handsets and Bluetooth interfaces.
For engineers reviewing the NCP152MX300280TCG 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 XDFN6 1.2×1.2 mm package compatibility with space-constrained portable designs.
Technical Context
The NCP152MX300280TCG integrates two independent PMOS-based LDO regulators sharing a common input but with separate EN1/EN2 controls and dedicated OUT1/OUT2 pins. Each channel employs bandgap-referenced feedback and current-limit protection, with thermal shutdown triggered at 160°C (140°C hysteresis).
Its architecture supports fast load transient response (<1 µs rise/fall) and eliminates need for noise-bypass capacitors via intrinsic low-noise design (75 µVrms, 10 Hz–100 kHz). The device operates across 1.9 V to 5.25 V input and maintains regulation down to 150 mV dropout at full 150 mA load on the 3.0 V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.0 V (OUT1) and 2.8 V (OUT2), fixed and independent - enables simultaneous powering of core logic and I/O rails |
| Max Output Current | 150 mA per channel - sufficient for baseband processors, RF transceivers, and sensor subsystems |
| Dropout Voltage | 150 mV typical at 150 mA on 3.0 V output - allows operation from single-cell Li-ion (3.0 V min) with margin |
| Quiescent Current | 50 µA per channel (typ) - extends battery life in always-on standby modes |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters in mixed-signal systems |
| Output Noise | 75 µVrms (10 Hz–100 kHz) - meets stringent RF PLL and ADC reference supply requirements |
| Enable Threshold | 0.9 V high / 0.4 V low - compatible with 1.8 V and 3.3 V GPIO without level-shifting |
Pinout & Package
Package: XDFN6 1.2 mm × 1.2 mm, 0.4 mm pitch, exposed thermal pad (Case 711AT). Designed for high-density PCB layouts and efficient heat dissipation via soldered GND pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 3.0 V output | Requires 0.22 µF ceramic capacitor to GND; supplies core voltage for microcontrollers or RF ICs |
| 2 - OUT2 | Regulated 2.8 V output | Independent 2.8 V rail for analog peripherals or memory I/O; decoupled separately |
| 3 - GND | Power ground | Common return path; exposed pad must be soldered to PCB GND plane for thermal and electrical integrity |
| 4 - EN2 | Enable for OUT2 | Active-high; <0.4 V disables OUT2 and activates 50 Ω active discharge to GND |
| 5 - IN | Input supply | Shared 1.9–5.25 V input for both channels; requires 0.22 µF ceramic capacitor close to pin |
| 6 - EN1 | Enable for OUT1 | Active-high; independent control allows staggered power-up or dynamic rail sequencing |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Ground Current | Reduces IQ to ~50 µA per channel at light load - critical for multi-day battery life in IoT sensors |
| Active Output Discharge | 50 Ω internal discharge path per output - ensures fast, controlled turn-off for system-level power sequencing |
| Stability with Small Capacitors | Guaranteed stable with ≥0.22 µF X7R/X5R ceramics - eliminates large tantalum caps and saves board area |
| Independent Dual Enable | EN1 and EN2 allow independent control of 3.0 V and 2.8 V rails - supports flexible power management firmware |
| Robust Protection | Per-channel current limit (280 mA typ), short-circuit tolerance, and thermal shutdown (160°C) - prevents cascade failures |

FAQ
What are the exact output voltages of the NCP152MX300280TCG?
The NCP152MX300280TCG provides fixed, factory-trimmed output voltages of 3.0 V on OUT1 and 2.8 V on OUT2. These values are specified over −40°C to +85°C junction temperature and are guaranteed within ±2% accuracy for VOUT > 2 V, per the onsemi datasheet revision 6 (October 2022). No external resistors or configuration pins are required to set these outputs.
Does the NCP152MX300280TCG require external capacitors for stability?
Yes, the NCP152MX300280TCG requires a 0.22 µF ceramic capacitor (X5R or X7R dielectric) placed close to each output pin (OUT1 and OUT2) and a 0.22 µF ceramic capacitor near the IN pin. The device is specifically designed to remain stable with this minimum capacitance and does not require additional ESR or bulk capacitance - simplifying layout and reducing bill-of-materials.
How does the active discharge feature work on the NCP152MX300280TCG?
When either EN1 or EN2 is driven below 0.4 V, the corresponding output (OUT1 or OUT2) is disabled and an internal 50 Ω discharge path connects that output to GND. This actively pulls the rail to ground within microseconds, preventing floating voltages or unintended wake-up events. The NCP152MX300280TCG implements this per-channel, allowing independent discharge control without external components.
What is the maximum input voltage rating for the NCP152MX300280TCG?
The absolute maximum input voltage for the NCP152MX300280TCG is 6 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating input voltage range is 1.9 V to 5.25 V. Operation above 5.25 V may cause permanent damage or violate safe operating area limits, even if within the 6 V absolute max - design margins should respect the 5.25 V operational ceiling.
Can the NCP152MX300280TCG operate from a single-cell Li-ion battery?
Yes, the NCP152MX300280TCG is explicitly designed for single-cell Li-ion operation. With a 3.0 V output and only 150 mV typical dropout at 150 mA, it maintains regulation down to 3.15 V input - well within the 3.0–4.2 V discharge curve of a standard Li-ion cell. Its 1.9 V minimum input also supports operation through full discharge, including protection cutoff regions.
