It is recommended to use a 1µF or larger ceramic capacitor from IN pin to ground to get a good power supply decoupling. 2 GND - Ground. 3 EN I Enable Pin. Drive EN high to turn on the regulator. Drive EN low to turn off the regulator. 4 NC/BYP - Do not connect (NC) or Connect a 10nF to ground to reduce output noise (BYP). 5 OUT O Regulator output voltage pin. A 2.2µF or larger ceramic capacitor from OUT to ground is required to ensure regulator stability.

The device is enabled when the enable pin voltage is greater than V IH(EN) and disabled with the enable pin voltage less than V IL(EN) . If independent control of chip enable is not needed, then connect the enable pin to the input. The LDO has an internal pulldown MOSFET that connects a discharge resistor from V OUT to ground when the device is disabled to actively discharge the output voltage. Output Current Limit When overload events happen, the output current is internally limited. Undervoltage Lockout (UVLO) The LDO uses an undervoltage lockout circuit to keep the output shut off until the internal circuitry is operating properly. Thermal Protection The LDO contains a thermal shutdown protection circuit to turn off the output current when excessive heat is dissipated in the LDO. 鼎研微电子 (www.dymicro.com) Company Confidential Rev 1.0, Page 6 DYW TLV700 PACKAGE OUTLINE DIMENSIONS SOT23-5 Dimensions (mm) Dimensions (mm) Symbol A Symbol Min Max 2.82 3.02 e 0.95 (BSC) Min Max C 1.05 1.15 C1 0.03 0.15 b 0.28 0.45 C2 0.12 0.23 B 1.50 1.70 L 0.35 0.55 B1 2.60 3.00 θ 0 8 鼎研微电子 (www.dymicro.com) Company Confidential Rev 1.0, Page 7
