Product details
Overview
NCP152MX180150TCG from onsemi is a dual-output, low-noise, low-quiescent-current linear voltage regulator delivering 150 mA per channel with independent enable control. It provides fixed 1.8 V and 1.5 V outputs in a compact XDFN6 (1.2 × 1.2 mm) package, features 150 mV typical dropout at full load, 75 dB PSRR at 1 kHz, and stable operation with only 0.22 µF ceramic output capacitors - ideal for RF-sensitive battery-powered applications like smartphones and wireless handsets.
For engineers reviewing the NCP152MX180150TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel independent enable logic, ultra-low ground current under light load (50 µA typical per channel), active output discharge, thermal shutdown with hysteresis, and compatibility with space-constrained PCB layouts requiring minimal external components.
Technical Context
The NCP152MX180150TCG integrates two independent PMOS-based LDO regulators sharing a common input rail but featuring separate EN1/EN2 control and dedicated OUT1/OUT2 pins. Each channel employs adaptive ground current optimization to reduce IQ below 100 µA at light loads while maintaining tight output regulation (±2% for VOUT > 2 V).
Its internal architecture includes bandgap reference, current-limit protection (280 mA typ.), thermal shutdown (160°C trip, 20°C hysteresis), and active discharge circuitry (50 Ω typical) activated when EN falls below 0.4 V - enabling fast, controlled turn-off without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 1.8 V (OUT1) and 1.5 V (OUT2); no external feedback required, simplifies layout and reduces BOM count. |
| Max Output Current | 150 mA per channel; supports simultaneous dual-rail powering of RF transceivers and baseband ICs. |
| Dropout Voltage | 150 mV typical at 150 mA (for 3.0 V input → 2.8 V output); enables efficient operation from single-cell Li-ion or Li-poly batteries. |
| Quiescent Current | 50 µA typical per enabled channel; critical for extending battery life in always-on sensor or BLE subsystems. |
| PSRR | 75 dB at 1 kHz; suppresses noise from noisy DC-DC converters feeding the LDO input, preserving signal integrity in RF front-ends. |
| Output Capacitor | Stable with ≥0.22 µF X5R/X7R ceramic; eliminates need for bulky tantalum or electrolytic caps, reducing footprint and cost. |
| Enable Threshold | EN high = ≥0.9 V, EN low = ≤0.4 V; compatible with standard GPIOs and allows independent sequencing of power rails. |
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 on 1 oz FR4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 1.8 V output | Supplies core voltage to low-power microcontrollers or RF ICs; requires 0.22 µF ceramic cap to GND for stability. |
| 2 - OUT2 | Regulated 1.5 V output | Provides I/O or analog supply for sensors or ADCs; decoupled independently to prevent cross-talk. |
| 3 - GND | Power ground reference | Must be connected to large copper pour; exposed pad (EP) soldered to GND plane for thermal and electrical performance. |
| 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 0.22 µF ceramic cap placed close to pin to minimize input impedance. |
| 6 - EN1 | Enable control for OUT1 | Independent control of 1.8 V rail; enables flexible power sequencing without external logic. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Ground Current | Reduces IQ to 50 µA/channel at light load, extending battery runtime in standby modes without sacrificing transient response. |
| Active Output Discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds upon disable, preventing floating voltages and ensuring clean reset behavior. |
| High PSRR & Low Noise | 75 dB PSRR at 1 kHz + 75 µVRMS output noise (10 Hz–100 kHz) enables direct powering of sensitive RF receivers without added filtering. |
| Thermal Shutdown w/ Hysteresis | 160°C trip / 140°C reset prevents latch-up during overload; channels operate independently, so one fault doesn't disable both rails. |
| Stable with Small Ceramic Caps | Guaranteed stability with 0.22 µF X7R/X5R MLCCs (0201/0402), eliminating ESR requirements and enabling ultra-compact designs. |

FAQ
What are the exact output voltages of the NCP152MX180150TCG?
The NCP152MX180150TCG provides fixed, factory-trimmed output voltages of 1.8 V on OUT1 and 1.5 V on OUT2. These values are non-adjustable and specified across −40°C to +85°C junction temperature with ±2% accuracy for VOUT > 2 V and ±60 mV for VOUT ≤ 2 V, as confirmed in the Electrical Characteristics table of the official datasheet.
Does the NCP152MX180150TCG require external capacitors for stability?
Yes - the NCP152MX180150TCG requires a 0.22 µF ceramic capacitor (X5R or X7R dielectric) on each output (OUT1 and OUT2) and a 0.22 µF ceramic capacitor on the IN pin. These are mandatory for stability and transient performance; the device is characterized and guaranteed stable only with these minimum values and no ESR requirement.
How does the enable functionality work on the NCP152MX180150TCG?
The NCP152MX180150TCG features two independent enable inputs: EN1 controls OUT1 and EN2 controls OUT2. Driving either EN pin above 0.9 V enables its respective output; driving it below 0.4 V disables the output and activates an internal 50 Ω discharge path to GND. Each EN pin has a 300 nA internal pull-down, ensuring default OFF state when unconnected.
What thermal protection features does the NCP152MX180150TCG include?
The NCP152MX180150TCG incorporates per-channel thermal shutdown with a 160°C trip point and 20°C hysteresis (reset at 140°C). This protection operates independently per output - a thermal fault on OUT1 does not affect OUT2 operation. The exposed pad must be soldered to GND for effective heat dissipation, as specified in the Thermal Characteristics section.
Is the NCP152MX180150TCG compatible with lead-free reflow processes?
Yes - the NCP152MX180150TCG is Pb-free and RoHS-compliant, qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Its XDFN6 package (Case 711AT) supports peak reflow temperatures up to 260°C, and the recommended mounting footprint and soldering guidelines are detailed in onsemi's Soldering and Mounting Techniques Reference Manual.
