SOT-23 (DBZ)-3-6.9204 mm² 2.92 x 2.37

The TLV803E, TLV809E, and TLV810E are enhanced alternatives to the TLV803, TLV853, TLV809, LM809, TPS3809 and TLV810. TLV80xE and TLV81xE offer low quiescent current I_Q, higher accuracy, wider temperature range, and lower power-on-reset (V_POR) for increased system reliability.

The TLV80xE and TLV81xE family are low I_Q (250 nA typical, 1 µA max), voltage supervisory circuits (reset IC) that monitor VDD voltage level. These devices initiate a reset signal whenever supply voltage VDD drops below the factory programmed falling threshold voltage, V_IT–. The reset output remains low for a fixed reset time delay t_D after the VDD voltage rises above the rising voltage threshold (V_IT+) which is equivalent to the falling threshold voltage (V_IT-) plus hysteresis (V_HYS).

These devices have integrated glitch immunity to ignore fast transients on the VDD pin. The low I_Q and high accuracy (±0.5% typical) makes these voltage supervisors ideal for use in low-power and portable applications. The TLV80xE and TLV81xE devices are specified to have the defined output logic state for supply voltages down to V_POR = 0.7 V. The TLV80xE and TLV81xE devices are available in industry standard 3-pin SOT23 (DBZ) and SC70 (DCK) packages and very compact X2SON (DPW) package.
