Product details
Overview
NCP152MX180280TCG from onsemi is a dual-output, 150 mA low-dropout linear voltage regulator with independent 1.8 V and 2.8 V outputs, 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 including smartphones and wireless interfaces.
For engineers reviewing the NCP152MX180280TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, active output discharge, stability with 0.22 µF ceramic capacitors, thermal shutdown, and XDFN6 1.2×1.2 mm package constraints.
Technical Context
The NCP152MX180280TCG integrates two independent PMOS-based LDO regulators sharing a common input but featuring separate EN1/EN2 control and OUT1/OUT2 outputs. Each channel employs adaptive ground current logic to minimize IQ under light load while maintaining tight output accuracy (±2% for VOUT > 2 V).
Its internal architecture includes dedicated current-limit and thermal shutdown circuits per channel, active discharge transistors (50 Ω typical), and bandgap reference circuitry enabling stable regulation across −40°C to +85°C without external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.8 V (OUT1) and 2.8 V (OUT2), fixed and independent - enables simultaneous power rail generation for core logic and RF subsystems |
| Max Output Current | 150 mA per channel - supports moderate-power digital ICs and analog front-ends without derating |
| Dropout Voltage | 160–260 mV at 150 mA (VOUT = 2.8 V) - allows operation from 3.0 V input while sustaining full load on 2.8 V rail |
| Quiescent Current | 50 µA typical per channel - extends battery life in always-on sensor or standby modes |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding the same VIN |
| Output Noise | 75 µVrms (10 Hz–100 kHz) - meets low-noise requirements for RF receivers and precision ADCs |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V GPIO logic and provides noise margin against supply ripple |
Pinout & Package
Package: XDFN6 1.2 mm × 1.2 mm, 0.4 mm pitch, exposed thermal pad (Case 711AT). Requires soldering of EP to GND for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 1.8 V output | Must connect 0.22 µF ceramic capacitor to GND; supplies core logic or processor I/O rails |
| 2 - OUT2 | Regulated 2.8 V output | Must connect 0.22 µF ceramic capacitor to GND; powers RF transceivers or analog sensors |
| 3 - GND | Power ground reference | Primary return path; exposed pad must be tied to PCB ground plane for thermal dissipation |
| 4 - EN2 | Enable control for OUT2 | Drives OUT2 ON when > 0.9 V; activates 50 Ω active discharge when < 0.4 V |
| 5 - IN | Common input supply | Accepts 1.9–5.25 V; requires local 0.22 µF ceramic bypass capacitor |
| 6 - EN1 | Enable control for OUT1 | Drives OUT1 ON when > 0.9 V; activates 50 Ω active discharge when < 0.4 V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable pins | EN1 and EN2 allow sequenced or asynchronous power-up/down of 1.8 V and 2.8 V rails - critical for SoC reset management |
| Active output discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds upon disable - prevents floating nodes and ensures clean state transitions |
| Stable with 0.22 µF ceramic output caps | Eliminates need for larger or higher-ESR capacitors - reduces BOM count and board area in space-constrained mobile designs |
| Adaptive ground current | Reduces IQ to ~50 µA at light load while maintaining regulation - improves efficiency during idle/sleep states |
| Thermal shutdown with hysteresis | Triggers at 160°C (TSD), resets at 140°C (TSDH) - protects device during sustained overload without latch-up |

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 |
|---|---|---|---|
| Torex XC6223D1828MR-G | Same 1.8 V/2.8 V outputs, 200 mA per channel, 350 mV dropout at 200 mA, no active discharge | Lacks active discharge and thermal hysteresis; higher dropout limits use below 3.15 V input | Select when higher output current is needed and active discharge is not required for system reset behavior |
| Richtek RT9080L-1828GB | 1.8 V/2.8 V outputs, 300 mA per channel, 250 mV dropout, integrated soft-start, no independent EN pins | Single enable pin controls both outputs; lacks per-channel enable flexibility and active discharge | Select when simplified control is acceptable and higher current capability justifies loss of independent sequencing |
Compared with XC6223D1828MR-G and RT9080L-1828GB, the NCP152MX180280TCG uniquely delivers per-channel enable control, active discharge, and lowest quiescent current (50 µA/channel) - making it optimal for systems requiring precise power sequencing and ultra-low standby power.

FAQ
What are the exact output voltages of the NCP152MX180280TCG?
The NCP152MX180280TCG delivers precisely 1.8 V on OUT1 and 2.8 V on OUT2. These are factory-trimmed fixed outputs with ±2% accuracy for VOUT > 2 V (i.e., 2.8 V rail) and ±60 mV for VOUT ≤ 2 V (i.e., 1.8 V rail), verified over −40°C to +85°C junction temperature range per the official onsemi datasheet Rev. 6.
Does the NCP152MX180280TCG require external capacitors, and what values are recommended?
Yes - the NCP152MX180280TCG requires a 0.22 µF X5R or X7R ceramic capacitor on IN, and one 0.22 µF ceramic capacitor per output (OUT1 and OUT2), placed as close as possible to their respective pins. These values ensure stability, transient response, and PSRR performance; larger values improve high-frequency rejection but are not required for basic operation.
How does the active discharge feature work in the NCP152MX180280TCG?
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 activates, pulling the output voltage to GND within microseconds. This prevents floating outputs and ensures deterministic state transitions - critical for systems with strict power sequencing requirements.
What is the maximum input voltage the NCP152MX180280TCG can tolerate?
The absolute maximum input voltage for the NCP152MX180280TCG is 6 V, but the recommended operating input voltage range is 1.9 V to 5.25 V. Operation above 5.25 V risks exceeding safe operating area limits and may trigger thermal shutdown or damage the device, even briefly.
Is the NCP152MX180280TCG pin-compatible with other variants in the NCP152 family?
Yes - all NCP152 variants, including NCP152MX180280TCG, share identical XDFN6 1.2×1.2 mm pinout and footprint (Case 711AT). Output voltage differences are implemented internally; no PCB layout change is needed when substituting between NCP152MX150280TCG, NCP152MX180280TCG, or NCP152MX330280TCG.
