Product details
Overview
AP7335-20SNG-7 from Diodes Incorporated is a fixed-output 2.0V, 300mA low-dropout linear regulator with enable control, 35μA quiescent current, 150mV dropout at full load, and stable operation with 1μF ceramic output capacitor. It serves as a primary power rail for baseband processors in portable electronics requiring fast transient response and ultra-low standby power.
For engineers reviewing the AP7335-20SNG-7 datasheet, AP7335-20SNG-7 pinout, AP7335-20SNG-7 application, or AP7335-20SNG-7 equivalent, key selection criteria include dropout voltage at 300mA, PSRR at 1kHz, thermal shutdown threshold, EN logic thresholds, and compatibility with 1μF low-ESR ceramic output capacitors in space-constrained DFN2020-6 layouts.
Technical Context
The AP7335-20SNG-7 integrates a PMOS pass transistor, bandgap reference, error amplifier, current-limit circuitry, and thermal shutdown comparator in a single monolithic IC. Its fixed 2.0V output is internally trimmed to ±2% accuracy across –40°C to +85°C ambient.
It operates from 2V to 6V input, delivers regulated output without minimum load, and features active-high enable with VIH = 1.4V and VIL = 0.4V. Fast 220μs startup and excellent load transient response (≤20mV deviation at 300mA step) support GSM/TDMA burst-mode power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% over –40°C to +85°C - ensures stable core voltage for 2.0V I/O or analog subsystems |
| Max Output Current | 300mA continuous - supports baseband DSPs, Bluetooth radios, and sensor hubs without derating at 85°C |
| Dropout Voltage | 150mV at 300mA (VOUT ≥ 2.5V), 170mV at 300mA (VOUT < 2.5V) - enables operation down to 2.17V input for 2.0V output |
| Quiescent Current | 35μA typical at no load - extends battery life in always-on wearable sensors and IoT endpoints |
| PSRR | 65dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails |
| Start-up Time | 220μs - meets real-time wake-up timing for GSM TDMA transmit bursts and MCU deep-sleep exit |
| Thermal Shutdown | 145°C trigger with 15°C hysteresis - provides self-recovery protection during sustained overload in sealed enclosures |
Pinout & Package
AP7335-20SNG-7 uses the DFN2020-6 package (2.0mm × 2.0mm × 0.6mm, 0.5mm pitch), thermally enhanced with exposed pad connected to GND. Pin 1 (EN) is top-left when marking dot is oriented top-left; pin 6 (NC) is bottom-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass close to pin to suppress input ripple and ensure stability |
| GND (Pin 2) | Power ground reference | Common return for IN, OUT, EN, and thermal pad; must be low-impedance plane for EMI and thermal performance |
| EN (Pin 1) | Enable control input | Active-high logic interface; drives internal pass transistor gate; VIH = 1.4V min ensures compatibility with 1.8V GPIO |
| OUT (Pin 4) | Regulated output | Delivers 2.0V ±2%; requires ≥1μF ceramic capacitor with ESR >15mΩ placed adjacent to pin for transient stability |
| NC (Pin 5 & 6) | No connection | Pins 5 and 6 are unconnected die pads; must be left floating or tied to GND per layout guidelines - not used for signal or thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >1-year battery life in coin-cell-powered BLE sensors operating at 1% duty cycle |
| Fast transient response | ≤20mV output deviation during 10mA→300mA load steps ensures clean supply for RF transceivers during TX/RX transitions |
| Stable with 1μF ceramic | Eliminates need for larger tantalum or aluminum electrolytic capacitors - reduces PCB area and cost in compact wearables |
| Integrated protection | Current limit (~600mA), short-circuit clamp (~140mA), and thermal shutdown prevent field failures in unattended edge devices |
| Green packaging | DFN2020-6 with halogen-free molding compound and RoHS-compliant lead finish meets IPC-1752A environmental compliance requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2002E/TO | 250mA max output, 175mV dropout at 250mA, 1.6μA IQ - lower current, higher dropout, ultra-low IQ | Best for sub-100mA sensor nodes where IQ dominates lifetime; unsuitable for 300mA GSM burst loads | Select only if load never exceeds 200mA and standby IQ <2μA is mandatory |
| Torex XC6210B202MR-G | 300mA, 120mV dropout at 300mA, 25μA IQ, but requires 4.7μF output cap - tighter dropout, lower IQ, higher capacitance demand | Preferred for ultra-thin designs needing lowest possible VIN-MIN; incompatible with 1μF-only layouts | Choose when input headroom is critical and board space allows ≥4.7μF ceramic |
Compared with MCP1700-2002E/TO and XC6210B202MR-G, AP7335-20SNG-7 uniquely balances 300mA capability, 150mV dropout, 35μA IQ, and 1μF stability - making it optimal for space-constrained, battery-powered GSM/Bluetooth platforms requiring full-load performance without capacitor overhead.

FAQ
What is the minimum input voltage required for AP7335-20SNG-7 to maintain 2.0V output at 300mA?
The minimum input voltage is 2.17V, calculated from the typical 170mV dropout voltage at 300mA for VOUT < 2.5V (per Electrical Characteristics table). At 25°C, the device sustains regulation down to VIN = VOUT + VDropout = 2.0V + 0.17V = 2.17V. Derating is required above 85°C due to increased dropout.
Can AP7335-20SNG-7 operate without an output capacitor?
No. The datasheet explicitly requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability. Omitting it causes oscillation and output voltage collapse under load. The capacitor must be placed adjacent to OUT and GND pins using short, wide traces per the recommended layout in DS32259 Rev. 3-2 page 14.
Is the NC pin on AP7335-20SNG-7 electrically isolated or thermally connected?
Pins 5 and 6 are true no-connect terminals - they are electrically isolated from all internal circuitry and provide no thermal conduction path. The datasheet specifies they must remain unconnected or tied to GND solely for mechanical anchoring; routing copper to them does not improve thermal performance.
Does AP7335-20SNG-7 support reverse-voltage protection?
No. The device lacks integrated reverse-polarity protection. Applying negative voltage to IN or OUT relative to GND can damage the internal PMOS pass transistor and bandgap circuitry. External Schottky diode or ideal diode controller is required in systems with potential reverse-battery or hot-swap conditions.
