Product details
Overview
AP7335-08SNG-7 from Diodes Incorporated is a 300mA fixed-output (0.8V) low-dropout linear regulator in DFN2020-6 package, featuring 35μA quiescent current, 150mV dropout at 300mA, 65dB PSRR at 1kHz, and integrated enable, thermal shutdown, and current-limit protection. It powers core logic rails in space-constrained portable devices requiring stable ultra-low-voltage supply.
For engineers reviewing the AP7335-08SNG-7 datasheet, AP7335-08SNG-7 pinout, AP7335-08SNG-7 application, or AP7335-08SNG-7 equivalent, key selection criteria include fixed 0.8V output accuracy (±2%), fast 220μs startup, stability with 1μF ceramic output capacitor, and operation across –40°C to +85°C ambient.
Technical Context
The AP7335-08SNG-7 implements a PMOS pass transistor architecture enabling low dropout and near-zero gate-drive current, directly supporting its 35μA quiescent current specification. Its internal 0.8V bandgap reference feeds a precision error amplifier that regulates output voltage without external feedback components.
Enable control is implemented as a logic-high active input with VIH ≥ 1.4V and VIL ≤ 0.4V, allowing direct interfacing with 1.8V/3.3V GPIO. Protection circuitry includes foldback current limiting (400–600mA), short-circuit clamping (~140mA), and thermal shutdown at 145°C with 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8V ±2% over –40°C to +85°C; enables powering of modern sub-1V processor cores and FPGA I/O banks. |
| Max Output Current | 300mA continuous; sufficient for single-core microcontrollers or sensor interface ICs in compact wearables. |
| Dropout Voltage | 150mV at 300mA (VOUT ≥ 2.5V); for 0.8V output, typical dropout is 170mV - allows operation from 1.0V input sources like single LiFePO₄ cells. |
| Quiescent Current | 35μA typical at zero load; reduces standby power loss in always-on subsystems such as RTC or BLE radio wake-up circuits. |
| PSRR | 65dB at 1kHz; suppresses switching noise from adjacent DC-DC converters feeding shared battery rails. |
| Startup Time | 220μs from EN high to regulated output; supports rapid power-state transitions in GSM/TDMA burst-mode applications. |
| Thermal Shutdown | Triggers at 145°C junction temperature with 15°C hysteresis; prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
AP7335-08SNG-7 uses the DFN2020-6 (2.0mm × 2.0mm, 0.65mm pitch) package with exposed thermal pad. Pin 1 is EN, Pin 2 is GND, Pin 3 is IN, Pin 4 is OUT, Pin 5 is NC, Pin 6 is NC. The package supports 251°C/W junction-to-ambient thermal resistance under standard FR-4 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-high logic control; must exceed 1.4V to activate regulator; ties directly to host MCU GPIO for dynamic power gating. |
| GND (Pin 2) | Power ground | Primary return path for IN, OUT, and internal bias currents; requires low-inductance connection to PCB ground plane. |
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V input; requires ≥1μF ceramic decoupling placed adjacent to pin to suppress supply noise and ensure stability. |
| OUT (Pin 4) | Regulated output | Delivers fixed 0.8V; requires ≥1μF ceramic capacitor with ESR >15mΩ placed within 2mm of pin for transient response and stability. |
| NC (Pins 5 & 6) | No connection | Internally unconnected; must remain floating or grounded per layout guidelines - no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 35μA quiescent current enables >1-year battery life in coin-cell–powered IoT sensors with 10s sleep cycles. |
| Fast transient response | Stable 0→300mA load steps with <20mV undershoot/overshoot; critical for powering burst-mode DSPs in voice-controlled edge devices. |
| Single-capacitor stability | Guaranteed stable with only 1μF ceramic output capacitor - eliminates need for costly tantalum or large MLCC arrays in space-limited designs. |
| Integrated protection suite | Combines current limit (600mA), short-circuit clamp (140mA), and thermal shutdown (145°C) - removes need for external fault-handling circuitry. |
| Green packaging | RoHS-compliant, halogen-free molding compound (no Br/Sb); meets IPC-1752A material declaration requirements for automotive and medical OEMs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-0802E/TO | 250mA max output, 1.6μA IQ, SOT23-5 package, 600mV dropout at 250mA | Lacks enable pin; unsuitable for dynamic power gating; higher dropout limits use with low-VIN sources | Select only if ultra-low IQ dominates over current capability and enable functionality. |
| Torex XC6210B082MR-G | 200mA max output, 1μA IQ, SOT25 package, 180mV dropout at 200mA, no thermal shutdown | No thermal protection; lower current rating restricts use to peripheral ICs, not processors | Prefer when board space permits SOT25 and thermal risk is mitigated by system-level derating. |
Compared with MCP1700-0802E/TO and XC6210B082MR-G, AP7335-08SNG-7 uniquely balances 300mA drive, 35μA IQ, integrated EN, and full protection set in a 2mm² DFN - making it optimal for next-gen sub-1V embedded systems where size, safety, and responsiveness are co-constrained.

FAQ
What is the minimum input voltage required for AP7335-08SNG-7 to regulate 0.8V output at 300mA?
The device requires VIN ≥ VOUT + VDROP = 0.8V + 0.17V = 0.97V minimum, but datasheet specifies absolute minimum VIN as 2.0V for guaranteed operation across temperature and process variation. Below 2.0V, performance parameters including PSRR and load regulation are not characterized.
Can AP7335-08SNG-7 operate without an output capacitor?
No. The device requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability and transient response. Omitting it causes oscillation and output voltage collapse under load, as confirmed in the Unstable Range plot on page 10 of DS32259 Rev. 3-2.
Is the EN pin 5V-tolerant when used with a 3.3V microcontroller?
Yes. EN pin absolute maximum rating is VIN + 0.3V, and VIN max is 6.5V. With VIN = 3.3V, EN accepts up to 3.6V - safely covering 3.3V GPIO logic-high levels. VIH threshold is 1.4V, ensuring reliable turn-on with standard CMOS outputs.
Does AP7335-08SNG-7 require a minimum load current to maintain regulation?
No. The datasheet explicitly states "no minimum load is required to keep the device stable" (page 10). It remains regulated and stable from zero load to 300mA, verified across –40°C to +85°C ambient conditions.
