Product details
Overview
AP7342D-3328FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, delivering fixed 3.3V and 2.8V outputs in a 1.2mm × 1.2mm X2-DFN1212-6 package. It features ±1% output voltage accuracy, 75dB PSRR at 1kHz, 60µVrms output noise (10Hz–100kHz), and ultra-low 35µA quiescent current in single-channel active mode-optimized for RF supply rails and camera sensor power in space-constrained portable electronics.
For engineers reviewing the AP7342D-3328FS6-7 datasheet, AP7342D-3328FS6-7 pinout, AP7342D-3328FS6-7 application, or AP7342D-3328FS6-7 equivalent, key selection criteria include dual-rail sequencing capability, high PSRR under light load, thermal performance in DFN1212, and compatibility with 0.47µF ceramic output capacitors without external compensation.
Technical Context
The AP7342D-3328FS6-7 integrates two independent CMOS-based LDO regulators sharing a common input (VIN) and ground (GND), each with dedicated enable (EN1/EN2) and output (VOUT1/VOUT2) pins. Its architecture supports simultaneous or staggered activation, with no internal discharge path unless enabled via the "D" variant designation-this part includes built-in auto-discharge for rapid VOUT ramp-down when disabled.
Each regulator employs a precision voltage reference and error amplifier to maintain tight regulation across –40°C to +85°C ambient, with dropout voltages as low as 0.22V at 150mA for the 3.3V rail and 0.26V for the 2.8V rail. Load transient response is stabilized by internal compensation compatible with 0.47µF ceramic output capacitors, eliminating need for external ESR tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3V (Channel 1) and 2.8V (Channel 2), fixed-enables dual-rail biasing for SoC core/I/O or RF transceiver/analog front-end without external feedback resistors. |
| Max Output Current | 150mA per channel-supports moderate-power sensors, audio codecs, or Wi-Fi/BT modules without thermal derating in typical PCB layouts. |
| PSRR | 75dB at 1kHz-rejects switching noise from adjacent DC-DC converters, critical for clean RF supply in smartphones and wireless adapters. |
| Output Noise | 60µVrms (10Hz–100kHz)-minimizes phase noise in local oscillators and jitter in high-speed data interfaces. |
| Quiescent Current | 35µA (single channel active), 70µA (both active)-extends battery life in always-on subsystems like touch controllers or ambient light sensors. |
| Dropout Voltage | 0.22V @ 150mA (3.3V rail), 0.26V @ 150mA (2.8V rail)-allows operation from single-cell Li-ion (3.0V min) with margin for voltage sag. |
| Enable Thresholds | VEN(H) ≥ 1.3V, VEN(L) ≤ 0.5V-compatible with 1.8V/3.3V GPIOs for precise power sequencing control. |
Pinout & Package
AP7342D-3328FS6-7 is housed in a 1.2mm × 1.2mm, 0.4mm height X2-DFN1212-6 package with exposed thermal pad. The pad must be connected to GND or large copper pour for thermal dissipation but not used as sole GND electrode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | 3.3V regulated output-connects directly to load requiring stable 3.3V rail; requires 0.47µF ceramic capacitor to GND within 2mm. |
| 2 | VOUT2 | 2.8V regulated output-powers noise-sensitive analog circuits; decoupling capacitor placement critical for PSRR performance. |
| 3 | GND | Common ground reference for both regulators-must tie to low-impedance system ground plane to minimize noise coupling. |
| 4 | EN2 | Active-high enable for Channel 2-driving low disables 2.8V output and reduces IQ to 0.1µA; floating prohibited. |
| 5 | VIN | Shared input (1.7V–5.25V)-requires 0.47µF ceramic capacitor to GND near pin to suppress supply glitches during load transients. |
| 6 | EN1 | Active-high enable for Channel 1-allows independent control of 3.3V rail; enables power sequencing (e.g., VOUT1 before VOUT2). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow staggered startup/shutdown-critical for meeting SoC power-up timing requirements (e.g., core before I/O). |
| Built-in auto-discharge | Internal 50Ω N-channel FET discharges VOUT1/VOUT2 when EN is low-reduces residual voltage to <100mV in <100µs, preventing latch-up in downstream logic. |
| Ultra-low noise & high PSRR | 60µVrms noise + 75dB PSRR enables direct powering of RF synthesizers without additional filtering stages. |
| Wide input range & low dropout | Operates from 1.7V up to 5.25V input with sub-0.25V dropout-supports single-cell Li-ion, USB VBUS, and multi-rail systems. |
| ±1% output accuracy | Tight tolerance over temperature and load ensures reliable operation of ADC references and memory I/O interfaces. |
Applications
| Smartphone Camera Module | Wi-Fi/Bluetooth Coexistence System |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7345D-3328FS6-7 | Successor with improved PSRR (80dB @ 1kHz), lower noise (45µVrms), and extended temp range (–40°C to +125°C); same pinout and footprint. | Required for new designs targeting AEC-Q100 automotive qualification or industrial applications above 85°C ambient. | Select AP7345D if long-term supply continuity, higher reliability, or extended temperature support is required. |
| TPL7407LPGDR | Single 7-channel high-side driver (not LDO); no voltage regulation, no low-noise capability-functionally incompatible. | Not suitable for voltage regulation tasks; only applicable for LED/gate driving where regulation is handled upstream. | Reject TPL7407LPGDR-misaligned function; does not meet LDO specification requirements. |
Compared with AP7342D-3328FS6-7, the AP7345D offers measurable improvements in noise, PSRR, and temperature rating while maintaining drop-in compatibility-making it the preferred choice for new designs. No true functional alternative exists among non-Diodes dual-LDOs with matching 1.2mm × 1.2mm DFN6 footprint and discharge capability.

FAQ
What is the thermal pad connection requirement for AP7342D-3328FS6-7?
The exposed thermal pad on the X2-DFN1212-6 package must be connected to a large copper pour tied to GND for optimal thermal dissipation. It should not serve as the sole GND electrode-minimum 20mm² copper area is recommended. Do not leave the pad floating or connect it to VIN or signal nets, as this degrades thermal performance and may cause instability.
Can AP7342D-3328FS6-7 operate with only one channel enabled?
Yes-EN1 and EN2 are fully independent. Enabling only EN1 delivers 3.3V at up to 150mA with 35µA quiescent current; EN2 can remain low (shutdown) to disable the 2.8V rail. This configuration reduces total system IQ by ~35µA versus dual-channel operation and is commonly used in partial-wake modes.
Is AP7342D-3328FS6-7 qualified for automotive applications?
No-AP7342D-3328FS6-7 is not AEC-Q100 qualified. Diodes explicitly states it is not recommended for new automotive designs. For automotive-grade dual-LDOs, the AP7345D series (AEC-Q100 Grade 2 qualified, –40°C to +125°C) is the designated replacement with identical pinout and enhanced specifications.
What output capacitor value is required for stable operation?
A minimum 0.47µF X5R/X7R ceramic capacitor is required per output (VOUT1 and VOUT2), placed within 2mm of the respective pin and GND. Larger values (e.g., 1.0µF) improve transient response but are not necessary for stability-the device is internally compensated for 0.47µF–10µF range with ESR <100mΩ.
