Product details
Overview
NCP152MX300300TCG from onsemi is a dual-output, low-noise, low-quiescent-current linear voltage regulator delivering two independent 3.0 V outputs at up to 150 mA each. 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-ideal for RF-sensitive battery-powered applications such as dual-rail smartphone baseband or connectivity subsystems.
For engineers reviewing the NCP152MX300300TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its matched dual 3.0 V outputs, adaptive ground current for light-load efficiency, active output discharge, thermal shutdown per channel, and XDFN6 1.2×1.2 mm footprint compatibility with space-constrained portable designs.
Technical Context
The NCP152MX300300TCG integrates two independent PMOS-based LDO regulators sharing a common input (IN) and ground (GND), each controlled by dedicated enable pins (EN1/EN2). Its bandgap reference and MOSFET drivers support tight output accuracy (±2% for VOUT > 2 V) and fast transient response without external compensation.
Each channel implements independent current limiting (~280 mA typ), thermal shutdown (160°C trip, 20°C hysteresis), and active discharge via a 50 Ω internal switch. The device operates across 1.9 V to 5.25 V input and maintains stability with minimal 0.22 µF X5R/X7R ceramic output capacitors-no noise bypass capacitor required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V / 3.0 V - matched dual fixed outputs; ±2% accuracy over −40°C to +85°C ensures reliable rail-to-rail logic interface compliance. |
| Max Output Current | 150 mA per channel - supports simultaneous powering of two low-power ICs (e.g., RF transceiver + MCU core) without derating. |
| Dropout Voltage | 150 mV typical at 150 mA - enables regulation from 3.15 V input, critical for Li-ion battery discharge down to 3.2 V. |
| Quiescent Current | 50 µA per channel - reduces standby power in always-on subsystems; drops to <1 µA in shutdown mode. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in RF receivers. |
| Output Noise | 75 µVRMS (10 Hz–100 kHz) - eliminates need for external noise filters in analog sensor or audio supply rails. |
| Enable Threshold | 0.9 V high / 0.4 V low - compatible with 1.8 V and 3.3 V GPIOs; internal 300 nA pull-down ensures safe default-off state. |
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).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 3.0 V output 1 | Connect 0.22 µF ceramic capacitor to GND; supplies first load (e.g., RF front-end bias rail). |
| 2 - OUT2 | Regulated 3.0 V output 2 | Independent second 3.0 V rail; supports separate sequencing or fault isolation from OUT1. |
| 3 - GND | Power ground reference | Common return path; must be tied to PCB ground plane and connected to exposed pad for thermal dissipation. |
| 4 - EN2 | Enable control for OUT2 | Drives >0.9 V to enable OUT2; <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 for transient immunity. |
| 6 - EN1 | Enable control for OUT1 | Independent enable for OUT1; allows staggered power-up or dynamic rail gating in multi-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow per-rail power control-enables flexible sequencing, dynamic power gating, and fault containment. |
| Active output discharge | 50 Ω internal discharge path pulls OUTx to GND within microseconds when disabled-prevents floating rails and ensures clean reset behavior. |
| Adaptive ground current | Reduces IQ to ~50 µA per channel at light load and <1 µA in shutdown-extends battery life in intermittent-use devices. |
| Stable with 0.22 µF ceramic capacitors | Eliminates need for larger or higher-ESR capacitors-reduces BOM count, board area, and cost in compact layouts. |
| Per-channel protection | Independent current limit (~280 mA), short-circuit protection, and thermal shutdown prevent single-point failure from affecting both outputs. |

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 TPS7A203030PDBVR | 3.0 V / 3.0 V dual LDO; 300 mA per channel; 165 mV dropout; 6.5 µA IQ; no active discharge. | Higher output current but lacks active discharge and per-channel thermal shutdown-less suitable for fault-critical RF isolation. | Select when higher current headroom is needed and active discharge is not required for system reset behavior. |
| Rohm BD3903FVM-CE2 | 3.0 V / 3.0 V dual LDO; 200 mA per channel; 250 mV dropout; 100 µA IQ; includes soft-start but no active discharge. | Slower transient response and higher dropout reduce usable input range below 3.3 V; no active discharge limits reset reliability. | Select when soft-start is prioritized over fast rail discharge and PSRR >70 dB is not mandatory. |
Compared with TPS7A203030PDBVR and BD3903FVM-CE2, the NCP152MX300300TCG delivers superior RF noise immunity (75 dB PSRR), faster fault recovery via active discharge, and tighter thermal protection granularity-making it optimal for space-constrained, battery-powered RF systems demanding robust dual-rail control.

FAQ
What are the exact output voltages of the NCP152MX300300TCG?
The NCP152MX300300TCG provides two precisely matched 3.0 V outputs, confirmed in the Ordering Information table (page 17) and Electrical Characteristics (page 4). Output voltage accuracy is ±2% over −40°C to +85°C for VOUT > 2 V, ensuring reliable operation with 3.0 V logic families and analog peripherals.
Does the NCP152MX300300TCG require external capacitors, and what values are recommended?
Yes-the NCP152MX300300TCG requires a 0.22 µF ceramic capacitor (X5R or X7R dielectric) on IN and each OUT pin, as specified in the Applications Information section (page 15). These capacitors 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 on the NCP152MX300300TCG?
When either EN1 or EN2 falls below 0.4 V, the corresponding output is disabled and an internal 50 Ω discharge transistor connects OUTx to GND. This rapidly discharges the output capacitor-verified in Figure 54 (page 14)-ensuring clean, predictable rail collapse for system reset and preventing back-powering of downstream circuitry.
What thermal protection mechanisms does the NCP152MX300300TCG implement?
The NCP152MX300300TCG includes per-channel thermal shutdown with a 160°C trip point and 20°C hysteresis (TSDH), as documented in the Electrical Characteristics table (page 4). Each regulator shuts down independently, allowing the unaffected channel to remain operational-a critical feature for fault-tolerant dual-rail systems.
Is the NCP152MX300300TCG pin-compatible with other variants in the NCP152 family?
Yes-all NCP152 variants, including NCP152MX300300TCG, use the identical XDFN6 1.2×1.2 mm package (Case 711AT) and share the same pinout (Figure 2, page 2). This allows drop-in replacement across voltage combinations (e.g., 3.0 V/3.0 V, 3.0 V/1.8 V) without PCB redesign-provided layout accommodates the specific marking rotation (0° for NCP152MX300300TCG).
