Product details
Overview
NCP152MX330280TCG from onsemi is a dual-output, low-noise, low-quiescent-current linear voltage regulator delivering 3.3 V and 2.8 V at up to 150 mA per channel. It 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-enabling compact RF power supply designs in space-constrained portable electronics.
For engineers reviewing the NCP152MX330280TCG datasheet, pinout, applications, or equivalent options, key selection criteria include independent enable control per channel, active output discharge, thermal shutdown with hysteresis, and XDFN6 1.2×1.2 mm package compatibility with high-density PCB layouts.
Technical Context
The NCP152MX330280TCG integrates two independent PMOS-based LDO regulators sharing a common input but with separate EN1/EN2 control and OUT1/OUT2 outputs. Each channel employs adaptive ground current logic to reduce IQ to 50 µA per channel under light load while maintaining fast transient response and low noise.
Its internal bandgap reference, current-limit circuitry (280 mA typ.), and thermal shutdown (160°C trip, 20°C hysteresis) operate independently per channel. The device requires no external noise-bypass capacitor and achieves stability with minimal 0.22 µF X7R/X5R ceramic output capacitance-optimized for battery-powered RF subsystems where PSRR and quiescent power are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3 V (OUT1) and 2.8 V (OUT2), fixed and independent-enables dual-rail power for baseband + RF ICs without external feedback resistors. |
| Max Output Current | 150 mA per channel-supports moderate-power processors, sensors, and wireless transceivers in portable devices. |
| Dropout Voltage | 140–220 mV at 150 mA (for 3.3 V/2.8 V outputs)-allows operation down to VIN = 3.44 V (3.3 V + 140 mV), extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 50 µA per channel (typ.)-reduces standby power loss in always-on subsystems such as Bluetooth® or ZigBee® receivers. |
| PSRR | 75 dB at 1 kHz-suppresses switching noise from DC-DC converters feeding the LDO input, critical for RF signal integrity. |
| Output Noise | 75 µVRMS (10 Hz–100 kHz)-meets stringent noise requirements of ADCs, PLLs, and RF front-ends without additional filtering. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V-ensures reliable turn-on/off with standard GPIOs and supports partial-system power gating. |
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 dissipation and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 3.3 V output | Connect 0.22 µF ceramic capacitor to GND; supplies core voltage for microcontrollers or I/O peripherals. |
| 2 - OUT2 | Regulated 2.8 V output | Connect 0.22 µF ceramic capacitor to GND; powers RF transceivers or analog sensors requiring lower rail. |
| 3 - GND | Power ground reference | Common return path; must be tied to PCB ground plane and exposed pad for thermal and noise performance. |
| 4 - EN2 | Enable control for OUT2 | Drive >0.9 V to enable 2.8 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 placed adjacent to pin to suppress high-frequency noise. |
| 6 - EN1 | Enable control for OUT1 | Drive >0.9 V to enable 3.3 V output; <0.4 V disables OUT1 and activates independent active discharge. |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual enable pins | EN1 and EN2 allow staggered or selective power-up/down of 3.3 V and 2.8 V rails-enabling dynamic power sequencing in multi-voltage SoC systems. |
| Active output discharge | 50 Ω internal discharge path per output pulls VOUT to GND within microseconds when disabled-prevents floating outputs and ensures clean reset behavior. |
| Stable with 0.22 µF ceramic COUT | Eliminates need for larger or higher-ESR capacitors, reducing BOM count and board area-ideal for 0402/0201 footprint constraints. |
| Adaptive ground current | Reduces IQ to 50 µA per channel at light load while maintaining regulation accuracy-extends battery life in sleep-mode applications. |
| Thermal shutdown with hysteresis | 160°C trip / 140°C reset prevents latch-up during overload; channels shut down independently-preserves functionality of unaffected rail during fault conditions. |

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 |
|---|---|---|---|
| TI TPS7A203328PDBVR | 3.3 V/2.8 V dual output; 300 mA per channel; 165 mV dropout at 300 mA; 6.5 µA IQ (single-channel active) | Higher current capability but larger 1.6×1.6 mm DSBGA package; no active discharge | Select when higher output current or lower IQ in single-rail mode is required; verify layout space and discharge timing constraints. |
| Rohm BD75L28G-M | Single 2.8 V LDO (150 mA); requires separate 3.3 V regulator; 120 mV dropout; 45 µA IQ; no active discharge | Discrete dual-LDO solution increases component count and board area; lacks independent enable per rail | Select only if 2.8 V is primary rail and 3.3 V can be sourced from another regulator; not suitable for tight sequencing or space-limited designs. |
Compared with TPS7A203328PDBVR and BD75L28G-M, the NCP152MX330280TCG uniquely combines matched dual-rail outputs, active discharge per channel, and XDFN6 footprint-making it optimal for miniaturized, multi-rail portable devices where sequencing, noise, and size are co-constrained.

FAQ
What are the exact output voltages of the NCP152MX330280TCG?
The NCP152MX330280TCG provides precisely 3.3 V on OUT1 and 2.8 V on OUT2. These are factory-trimmed fixed outputs-no external resistors or programming are required. Output voltage accuracy is ±2% for VOUT > 2 V, ensuring reliable operation for 3.3 V I/O and 2.8 V RF circuits without calibration.
Does the NCP152MX330280TCG require external capacitors for stability?
Yes-the NCP152MX330280TCG 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 values are validated for stability across temperature and load; using smaller or higher-ESR capacitors may cause oscillation or poor transient response.
How does the active discharge feature work in the NCP152MX330280TCG?
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 connects the output to GND. This rapidly discharges the output capacitor-ensuring VOUT reaches near-zero volts within microseconds, preventing unintended device wake-up or latch-up in power-gated systems.
What is the maximum input voltage rating for the NCP152MX330280TCG?
The absolute maximum input voltage for the NCP152MX330280TCG is 6 V. However, the recommended operating input voltage range is 1.9 V to 5.25 V. Exceeding 5.25 V may degrade long-term reliability or trigger overvoltage protection not specified in the datasheet; sustained operation above 6 V will damage the device.
Can the NCP152MX330280TCG be used in automotive applications?
The NCP152MX330280TCG is not AEC-Q200 qualified and is specified for −40°C to +85°C operation-suitable for consumer and industrial environments but not for under-hood automotive use. For automotive-grade dual LDOs, consider onsemi's NCV8170 or NCV8184 families, which offer extended temperature range and qualification compliance.
