Product details
Overview
SIP21107DR-30-E3 from Vishay Siliconix is a 3.0 V fixed-output, 150 mA low-noise, low-dropout linear regulator with Power-OK (POK) error flag output and no external bypass capacitor requirement. It features 135 mV dropout at 150 mA, ±2.5 % output voltage accuracy over -40 °C to +85 °C, and 35 µA ground current at 1 mA load - optimized for battery-powered RF systems such as wireless handsets and digital cameras.
For engineers reviewing the SIP21107DR-30-E3 datasheet, SIP21107DR-30-E3 pinout, SIP21107DR-30-E3 application, or SIP21107DR-30-E3 equivalent, key selection criteria include POK functionality, SC70-5L package footprint, 3.0 V fixed output, thermal shutdown at 160 °C, and compatibility with 1 µF ceramic output capacitors without stability compensation.
Technical Context
The SIP21107DR-30-E3 uses an internal P-channel MOSFET pass transistor (0.9 Ω typical RDS(on)) and a 1.2 V bandgap reference to regulate output voltage. Its error amplifier compares feedback from the fixed internal resistor divider against the reference to control gate drive.
POK operation is implemented via an open-drain NMOS comparator monitoring VOUT relative to VIN, asserting low when output falls below 90–96 % of nominal (e.g., <2.7 V for 3.0 V output). Shutdown mode reduces supply current to ≤1 µA and activates a 100 Ω internal discharge path from VOUT to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2.5 % over -40 °C to +85 °C - ensures stable core logic supply in portable devices. |
| Dropout Voltage | 135 mV at 150 mA load - enables regulation down to VIN = 3.135 V, extending usable battery range. |
| Ground Current | 35 µA typical at 1 mA load - minimizes quiescent drain during light-load standby. |
| Shutdown Current | ≤1 µA at 85 °C - preserves battery life in deep-sleep modes. |
| POK Threshold | 90–96 % of VOUT (2.7–2.88 V for 3.0 V output) - provides precise under-voltage detection before system reset. |
| Output Current Limit | 330 mA typical short-circuit protection - prevents damage during transient faults without external circuitry. |
| Auto-Discharge Resistance | 100 Ω typical - discharges 1 µF output cap to <10 % in <1 ms after shutdown. |
Pinout & Package
Package: SC70-5L (2.1 mm × 2.1 mm × 0.95 mm), RoHS-compliant, industrial temperature range (-40 °C to +85 °C).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control; <0.4 V disables regulator and triggers auto-discharge. |
| 2 (GND) | Ground reference | Primary thermal and electrical return; must connect to large PCB ground plane for thermal management. |
| 3 (VIN) | Input supply | Accepts 2.2–6.0 V; requires 1 µF ceramic bypass capacitor to GND for noise rejection. |
| 4 (VOUT) | Regulated output | Delivers 3.0 V ±2.5 %; stable with ≥1 µF ceramic output capacitor (ESR < 0.4 Ω). |
| 5 (POK) | Power-OK open-drain flag | Requires external pull-up to VIN or VOUT; goes low on dropout, overcurrent, or thermal shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| No external noise bypass capacitor required | Eliminates 10 nF BP capacitor needed by SiP21106, reducing BOM count and board area. |
| Integrated POK (Power OK) flag | Provides system-level power sequencing and fault monitoring without external comparators or resistors. |
| Auto-discharge on shutdown | 100 Ω internal NMOS pulls VOUT to GND within 1 ms, preventing back-powering of upstream circuitry. |
| Thermal and short-circuit protection | Shuts down at 160 °C junction temperature and limits output to 330 mA, enabling robust operation in unattended applications. |
| Stable with 1 µF ceramic output capacitor | Reduces component cost and footprint versus tantalum or larger ceramics; supports X7R/Y7R dielectrics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 300 mA output, 1.6 µA quiescent current, no POK pin, SOT-23-5 package | Lacks power-good signaling; suited for ultra-low-IQ applications where fault monitoring is handled externally | Select when lowest possible standby current is critical and POK is not required. |
| TLC7733QPWRQ1 | Automotive-grade (-40 °C to +125 °C), integrated reset timer, 250 mA output, TSSOP-8 package | Includes programmable delay reset function; larger footprint and higher cost than SC70-5L | Select for automotive infotainment modules requiring AEC-Q100 qualification and reset coordination. |
Compared with MCP1700T-3002E/TT and TLC7733QPWRQ1, the SIP21107DR-30-E3 uniquely combines SC70-5L miniaturization, integrated POK, and 150 mA capability - making it optimal for space-constrained consumer portables where real-time power status is essential but automotive qualification is unnecessary.

FAQ
What is the maximum input voltage rating for the SIP21107DR-30-E3?
The SIP21107DR-30-E3 has an absolute maximum input voltage of 6.5 V. Operation above this level risks permanent damage. The recommended operating range is 2.2 V to 6.0 V, ensuring reliable regulation across lithium-ion battery discharge profiles and USB-powered systems.
Does the SIP21107DR-30-E3 require an external pull-up resistor on the POK pin?
Yes, the SIP21107DR-30-E3 POK pin is an open-drain NMOS output and requires an external pull-up resistor to either VIN or VOUT. Typical values range from 10 kΩ to 100 kΩ; the internal POK sink can drive up to 0.5 mA while maintaining valid logic levels.
Can the SIP21107DR-30-E3 be used with ceramic output capacitors smaller than 1 µF?
No - the SIP21107DR-30-E3 is specified for stable operation only with ≥1 µF ceramic output capacitance (ESR < 0.4 Ω). Using smaller values may cause oscillation or degraded load-transient response, as confirmed in the stability analysis section of Document Number 74442.
What is the thermal shutdown behavior of the SIP21107DR-30-E3?
The SIP21107DR-30-E3 enters thermal shutdown at approximately 160 °C junction temperature and resumes normal operation once the junction cools by ~20 °C. During sustained overload, this results in pulsed output - a safety mechanism that prevents permanent damage but requires proper PCB thermal design to avoid continuous cycling.
Is the SIP21107DR-30-E3 still in production or available for new designs?
The SIP21107DR-30-E3 is End of Life per Vishay's announcement: last available purchase date was December 31, 2014. Aetrix Electronics maintains legacy inventory and supports obsolescence management, including cross-reference guidance and long-term supply planning for existing production programs.
