Product details
Overview
AP7342-3028FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, delivering fixed 3.0V and 2.8V outputs in a 1.2mm × 1.2mm X2-DFN1212-6 package. It features ±1% output voltage accuracy over temperature, 75dB PSRR at 1kHz, 60µVrms output noise (10Hz–100kHz), and quiescent current as low as 35µA per active channel - optimized for RF supply rails and portable media subsystems.
For engineers reviewing the AP7342-3028FS6-7 datasheet, AP7342-3028FS6-7 pinout, AP7342-3028FS6-7 application, or AP7342-3028FS6-7 equivalent, key selection criteria include dual independent enable logic, ultra-low noise for sensitive analog/RF stages, tight DC accuracy under load transients, and thermal performance in space-constrained handheld PCB layouts.
Technical Context
The AP7342-3028FS6-7 integrates two CMOS-based LDO regulators sharing a common input (VIN) and ground (GND), each with dedicated EN1/EN2 control and VOUT1/VOUT2 outputs. Its architecture supports independent shutdown of either channel without affecting the other, enabling dynamic power sequencing in multi-rail systems.
Each regulator uses an internal resistor network to set its fixed output (3.0V and 2.8V), employs low-RDS(on) pass devices for sub-300mV dropout at 150mA, and includes foldback short-circuit protection (~55mA) and thermal shutdown - all operating across −40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.0V (Channel 1) and 2.8V (Channel 2), fixed via internal resistor network - eliminates external feedback components and ensures stable rail generation. |
| Max Output Current | 150mA per channel - sufficient to power baseband processors, camera ISPs, or RF front-end bias circuits without external boost. |
| PSRR | 75dB at 1kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Output Noise | 60µVrms (10Hz–100kHz) - preserves signal integrity in ADC reference supplies and RF synthesizer VCOs. |
| Quiescent Current | 35µA per active channel - extends battery life in always-on sensor or standby communication subsystems. |
| Dropout Voltage | 250mV max at 150mA (for 3.0V output); 290mV max (for 2.8V output) - enables operation from single-cell Li-ion (3.0V min) with margin. |
| Accuracy | ±1% at +25°C; ±1.5% over −40°C to +85°C - meets tight tolerance requirements for memory I/O and core logic supplies. |
Pinout & Package
X2-DFN1212-6 package: 1.2mm × 1.2mm body, 0.4mm pitch, thermally enhanced with exposed pad (non-functional GND connection recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | Regulated 3.0V output - connects directly to load; requires local 0.47µF ceramic capacitor for stability. |
| 2 | VOUT2 | Regulated 2.8V output - independently controllable; decoupled with separate 0.47µF ceramic capacitor. |
| 3 | GND | Analog/digital ground reference - must be tied to low-impedance PCB ground plane; thermal pad connected to GND improves heat dissipation. |
| 4 | EN2 | Active-high enable for Channel 2 - drives high (>1.3V) to activate 2.8V rail; floating prohibited. |
| 5 | VIN | Common input (1.7V–5.25V) - shared by both regulators; requires 0.47µF ceramic capacitor placed near pin. |
| 6 | EN1 | Active-high enable for Channel 1 - controls 3.0V rail independently; compatible with GPIOs or power sequencer outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow staggered power-up/down of 3.0V and 2.8V rails - essential for I/O/core sequencing in mobile SoCs. |
| Ultra-low output noise | 60µVrms (10Hz–100kHz) - avoids phase noise degradation in RF transceivers and jitter in high-speed interfaces. |
| High PSRR at low frequency | 75dB at 1kHz - rejects ripple from buck converter switching frequencies and their harmonics. |
| Low quiescent current | 35µA per active channel - minimizes standby power in battery-backed real-time clocks and sensor hubs. |
| Thermally efficient DFN package | X2-DFN1212-6 with exposed pad - achieves 210°C/W θJA (typ.) on 2-layer board, supporting 150mA continuous per channel. |
Applications
| Smartphone Baseband Power | RF Front-End Bias |
|---|---|
|
Use Scenario: Powering application processor I/O banks and modem subsystems requiring tightly regulated 3.0V and 2.8V rails. IC Role / Device Role / Timing Role: Dual-LDO providing independent, low-noise, sequenced voltage domains for digital baseband and connectivity peripherals. Use Value: Eliminates need for two discrete regulators while maintaining <±1.5% accuracy across temperature and load - reducing BOM count and PCB area by 40% vs. single-channel alternatives. |
Use Scenario: Supplying low-noise bias to PA drivers, LNAs, and mixer stages in 4G/5G RF modules. IC Role / Device Role / Timing Role: Clean 2.8V rail for RF amplifier bias and 3.0V for synthesizer VCO tuning - isolated from digital switching noise. Use Value: 60µVrms noise and 75dB PSRR prevent AM-to-PM conversion and phase noise degradation - improving EVM by >2dB in LTE transmission. |
| Portable Camera ISP | Wireless Adapter Core Logic |
|

IC Role / Device Role / Timing Role: Dual-output LDO ensuring simultaneous, low-ripple power for ISP core and high-speed serial interface logic. Use Value: Independent EN control allows synchronized startup with sensor initialization sequence - reducing boot time by 12ms vs. daisy-chained regulators. |
Use Scenario: Powering Wi-Fi/BT combo chip cores (2.8V) and I/O buffers (3.0V) in USB dongles and IoT edge nodes. IC Role / Device Role / Timing Role: Compact dual-rail regulator enabling single-input, dual-voltage operation from 3.3V or 3.6V battery sources. Use Value: 1.2mm × 1.2mm footprint saves >1.5mm² vs. SOIC-8 equivalents - critical for sub-10mm² wireless adapter PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7345D-3028FS6-7 | Successor device with identical pinout, same 3.0V/2.8V outputs, but adds auto-discharge function and improved PSRR (80dB @ 1kHz). | Required where rapid VOUT discharge after shutdown is needed (e.g., hot-swap interfaces); not drop-in if discharge is unused. | Select when designing new products - Diodes explicitly states AP7342 is not recommended for new designs. |
| TPL7407LDR | Single-channel 250mA LDO (3.0V only), no dual output or EN2; 50µVrms noise, 65dB PSRR @ 1kHz. | Suitable only for single-rail use cases; requires second regulator for 2.8V, increasing layout complexity and cost. | Consider only if 2.8V rail is sourced elsewhere - lacks integrated dual-channel efficiency and sequencing capability. |
Compared with AP7342-3028FS6-7, the AP7345D-3028FS6-7 offers higher PSRR and built-in discharge without footprint change, while TPL7407LDR forces duplication of regulation circuitry and forfeits independent enable control - making the AP7342 viable only for legacy design refresh or cost-sensitive replacements where discharge is irrelevant.

FAQ
Is AP7342-3028FS6-7 pin-compatible with AP7345D-3028FS6-7?
Yes - both share identical X2-DFN1212-6 packaging and pin mapping (VOUT1, VOUT2, GND, EN2, VIN, EN1). The AP7345D adds auto-discharge functionality but maintains full electrical and mechanical compatibility, allowing direct replacement in existing layouts where discharge behavior is acceptable or unused.
What is the maximum allowable input voltage for AP7342-3028FS6-7?
The absolute maximum input voltage is 6.0V, but the recommended operating range is 1.7V to 5.25V. Exceeding 5.25V risks violating safe operating area limits and may trigger thermal shutdown or permanent damage, especially under full 150mA load per channel.
Can EN1 and EN2 be tied together and driven by a single GPIO?
Yes - EN1 and EN2 can be paralleled and driven by one microcontroller GPIO, enabling simultaneous on/off control of both 3.0V and 2.8V outputs. However, this forfeits independent sequencing; ensure the GPIO can source/sink ≥2µA total leakage current and swing above 1.3V (VIH) and below 0.5V (VIL).
Does AP7342-3028FS6-7 require external capacitors, and what values are recommended?
Yes - a minimum 0.47µF ceramic capacitor is required between VIN and GND, and separate 0.47µF ceramics must be placed at VOUT1 and VOUT2 pins. These must be located within 2mm of respective pins with low-inductance traces to ensure stability, transient response, and PSRR performance as specified in the datasheet.
