Product details
Overview
NCP152MX150280TCG from onsemi is a dual-output, low-noise, low-quiescent-current linear voltage regulator delivering 150 mA per channel with independent 1.5 V and 2.8 V outputs. It features 150 mV typical dropout at 150 mA (for 2.8 V output), 75 dB PSRR at 1 kHz, and stable operation with only 0.22 µF ceramic output capacitors - ideal for RF-sensitive battery-powered applications such as wireless handsets and Bluetooth interfaces.
For engineers reviewing the NCP152MX150280TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, adaptive ground current under light load, active output discharge, thermal shutdown per channel, and XDFN6 1.2×1.2 mm package compatibility with space-constrained portable designs.
Technical Context
The NCP152MX150280TCG integrates two independent PMOS LDO regulators sharing a common input but with separate EN1/EN2 controls and dedicated OUT1/OUT2 pins. Each channel employs bandgap-referenced error amplification, current-limit protection (280 mA typ), and thermal shutdown (160°C trip, 20°C hysteresis) operating autonomously.
Its adaptive ground current architecture reduces IQ to 50 µA per channel at no load and scales with output current, while active discharge (50 Ω typical) ensures fast turn-off of each output when its enable pin falls below 0.4 V - critical for power sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.5 V (OUT1) and 2.8 V (OUT2) - fixed, factory-trimmed, ±2% accuracy for VOUT > 2 V |
| Max Output Current | 150 mA per channel - sustained delivery without thermal shutdown under proper PCB copper area |
| Dropout Voltage | 160 mV typical at 150 mA for 2.8 V output - enables regulation from 2.96 V input minimum |
| Quiescent Current | 50 µA per channel (typ) at no load - extends battery life in always-on subsystems |
| PSRR | 75 dB at 1 kHz - suppresses noise from noisy shared supply rails in RF front-ends |
| Output Noise | 75 µVRMS (10 Hz–100 kHz) - eliminates need for external noise-bypass capacitors |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V and 3.3 V logic without level shifters |
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 on 1 oz FR4 with 645 mm² Cu).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 1.5 V output | Connect 0.22 µF ceramic capacitor to GND; supports up to 150 mA load |
| 2 - OUT2 | Regulated 2.8 V output | Independent from OUT1; requires own 0.22 µF ceramic capacitor |
| 3 - GND | Power ground reference | Common return for both channels; must be tied to exposed pad for thermal dissipation |
| 4 - EN2 | Enable control for OUT2 | Logic-high (>0.9 V) enables OUT2; <0.4 V disables OUT2 and activates 50 Ω discharge path |
| 5 - IN | Input supply (1.9–5.25 V) | Shared input for both regulators; requires 0.22 µF ceramic capacitor close to pin |
| 6 - EN1 | Enable control for OUT1 | Independent logic control for 1.5 V rail; internal 300 nA pull-down ensures default OFF state |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow staggered power-up/down sequencing between 1.5 V and 2.8 V rails |
| Active output discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds upon disable |
| Stable with minimal capacitance | Guaranteed stability with 0.22 µF X5R/X7R ceramic capacitors - no ESR requirements |
| Per-channel protection | Independent current limit (280 mA typ) and thermal shutdown (160°C) prevent cross-channel failure propagation |
| Ultra-low noise operation | 75 µVRMS noise (10 Hz–100 kHz) eliminates need for external noise-filtering components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A202815PDBVR | 1.5 V/2.8 V dual output; 300 mA per channel; higher IQ (65 µA); same X2SON-6 package | Higher output current margin but larger dropout (200 mV @ 150 mA for 2.8 V) | Choose when higher load headroom or tighter load regulation is required; verify thermal design for 300 mA continuous use |
| MAX1725ETA+T | Single 2.8 V output only; 200 mA; 125 µA IQ; SOT-23-5 package; no second output or EN2 | Lacks dual-rail capability and independent enable - requires additional regulator for 1.5 V rail | Only suitable if system redesign allows separation of 1.5 V supply; not a drop-in replacement |
Compared with TPS7A202815PDBVR and MAX1725ETA+T, the NCP152MX150280TCG uniquely delivers matched 1.5 V/2.8 V outputs with lowest dropout (160 mV), lowest noise (75 µVRMS), and per-channel enable/discharge - making it optimal for space- and noise-constrained dual-rail portable designs.

FAQ
What are the exact output voltages of the NCP152MX150280TCG?
The NCP152MX150280TCG provides precisely trimmed fixed outputs: OUT1 delivers 1.5 V ±2% (for VOUT > 2 V specification) and OUT2 delivers 2.8 V ±2%, confirmed in the Ordering Information table and Electrical Characteristics section of the official datasheet. These values are factory-set and non-adjustable.
Does the NCP152MX150280TCG require external capacitors for stability?
Yes - the NCP152MX150280TCG requires a 0.22 µF X5R or X7R ceramic capacitor on each output (OUT1 and OUT2) and one on the IN pin, all placed as close as possible to their respective pins. The device is guaranteed stable with these values and does not require ESR tuning or additional bypass components.
How does the active discharge function work on the NCP152MX150280TCG?
When either EN1 or EN2 falls 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 rapidly discharges external capacitors - critical for safe power sequencing and preventing back-driving in multi-rail systems.
What is the maximum input voltage the NCP152MX150280TCG can tolerate?
The absolute maximum input voltage for the NCP152MX150280TCG is 6 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating range is 1.9 V to 5.25 V. Exceeding 6 V risks permanent damage, even momentarily.
Is the NCP152MX150280TCG RoHS-compliant and Pb-free?
Yes - the NCP152MX150280TCG is explicitly marked "Pb-Free" in the Ordering Information and carries the "G" suffix per onsemi's packaging standard. It complies with RoHS Directive 2011/65/EU and is suitable for lead-free reflow assembly processes.
