Product details
Overview
AP7333-10SAG-7 from Diodes Incorporated is a 300mA, fixed 1.0V output, low dropout linear regulator in SOT23 package with 65µA quiescent current, 300mV dropout at full load, and 65dB PSRR at 100Hz-designed for battery-powered wireless LAN cards and XDSL routers requiring stable low-power voltage regulation.
For engineers reviewing the AP7333-10SAG-7 datasheet, AP7333-10SAG-7 pinout, AP7333-10SAG-7 application, or AP7333-10SAG-7 equivalent, key selection criteria include ultra-low IQ across input range (2–6V), fast 80µs startup, stability with 1µF ceramic output capacitor, and integrated thermal shutdown, current limit, and short-circuit protection.
Technical Context
The AP7333-10SAG-7 integrates a PMOS pass element, band-gap reference, error amplifier, and protection circuitry to deliver regulated 1.0V output with minimal dropout and near-constant 65µA quiescent current from 0 to 300mA load. Its architecture enables fast transient response without external compensation.
It operates across 2V–6V input, maintains ±2% output accuracy over –40°C to +85°C ambient, and achieves 0.01–0.20%/V line regulation and ±0.6% load regulation-enabling reliable operation in noise-sensitive digital baseband circuits with rapidly switching loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±2% - ensures precise core voltage for low-voltage logic in portable SoCs. |
| Max Output Current | 300mA continuous - supports moderate-power RF transceivers and microcontrollers. |
| Quiescent Current | 65µA typical at full load - extends battery life in always-on standby modes. |
| Dropout Voltage | 300mV typical at 300mA - allows operation down to 1.3V input for single-cell Li-ion or NiMH systems. |
| PSRR | 65dB at 100Hz - suppresses power supply ripple from switching converters feeding the LDO input. |
| Start-up Time | 80µs - enables rapid wake-up from deep sleep without voltage droop on critical rails. |
| Stability | Guaranteed with 1µF X7R/X5R ceramic output capacitor - reduces BOM count and PCB area. |
Pinout & Package
SOT23-3 package: compact 2.9mm × 1.6mm surface-mount outline with gull-wing leads, RoHS-compliant lead-free finish, and green molding compound (no Br/Sb).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2–6V DC; requires ≥1µF ceramic bypass capacitor placed adjacent to pin for noise rejection. |
| 2 (OUT) | Regulated output | Delivers stable 1.0V; connects directly to load with short trace to minimize inductance and overshoot. |
| 3 (GND) | Ground reference | Common return path for IN and OUT; must be tied to low-impedance ground plane to ensure PSRR and thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 65µA across full 0–300mA load and 2–6V input range-minimizes no-load battery drain in IoT sensors. |
| Fast transient response | Stable 0→300mA load step with <50mV undershoot/overshoot-supports GSM TDMA burst-mode operation. |
| Integrated protection | Thermal shutdown (140°C), current limit (~600mA), and short-circuit clamp (~100mA)-eliminates need for external fault management. |
| No minimum load requirement | Maintains regulation at 0mA output-simplifies design for intermittent-load applications like wake-on-RF modules. |
Applications
| Wireless LAN Cards | XDSL Routers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1002E/TT (Microchip) | 250mA max, 1.8µA IQ, 600mV dropout at 250mA, SOT23-3 | Lower IQ but lower current rating and higher dropout-unsuitable for 300mA burst loads. | Select only for sub-200mA always-on sensor nodes where ultra-low IQ outweighs current capability. |
| TPS7A0510PDBVR (TI) | 200mA max, 25µA IQ, 170mV dropout at 200mA, SOT23-5 (enable pin) | Includes enable control and lower dropout, but rated only to 200mA and requires 5-pin layout. | Prefer when system-level enable sequencing is required and peak load stays ≤200mA. |
Compared with MCP1700T-1002E/TT and TPS7A0510PDBVR, the AP7333-10SAG-7 uniquely balances 300mA drive, 65µA IQ, and 300mV dropout in a 3-pin SOT23-making it optimal for space-constrained, battery-fed devices needing robust transient response without enable logic.

FAQ
What is the minimum input voltage required for stable 1.0V output at 300mA?
The AP7333-10SAG-7 requires VIN ≥ 1.3V to maintain regulation at 300mA due to its 300mV typical dropout voltage. Below this, output collapses; operation is specified from 2V to 6V input for guaranteed performance across temperature and process variation.
Can the AP7333-10SAG-7 operate without an output capacitor?
No-while the device remains stable with only 1µF ceramic output capacitance, zero output capacitance causes oscillation and loss of regulation. The datasheet explicitly requires ≥1µF X7R/X5R ceramic capacitor between OUT and GND for all operating conditions.
Does the AP7333-10SAG-7 have an enable pin or shutdown function?
No-the AP7333-10SAG-7 has no enable input or shutdown mode. It operates continuously when VIN is within 2–6V. For on/off control, external MOSFET switching on the input rail is required.
How does thermal shutdown behave under sustained overload?
When junction temperature reaches ~140°C, thermal shutdown disables the output; recovery occurs at ~125°C hysteresis. Under continuous overload, this causes on-off cycling-limiting average power dissipation but not preventing damage if ambient exceeds 85°C or PCB copper area is insufficient.
