Once the input voltage reaches approximately 1V, the power-on reset circuit enables the device as long as the SHDN pin is held high. SHUTDOWN The SHDN pin allows the LX1882 to be enabled or disabled. A logic zero (0.4V) on the SHDN pin places the LX1882 in shutdown mode, reducing the supply current to < 5uA and connecting VOUT to ground through a 100Ω switch. In addition, CPO will be high impedance and disconnected from VIN. If the shutdown feature is not required, connect SHDN to VIN to continuously enable the part. Current Limit Protection The LX1882 includes over current protection. When the output load current exceeds typically 60mA, the circuit forces the regulator output to decrease. Temperature Protection The thermal protection shuts the LX1882 down when the junction temperature exceeds 1400C. Exposure to absolute maximum rated conditions for extended periods may affect device reliability (see Thermal Considerations below). THERMAL CONSIDERATIONS Thermal shutdown protects the circuit from thermal overload caused from a rise in junction temperature during power dissipation. This means of protection is intended for fault protection only and not as a means from current or power limiting during normal application usage. Proper thermal evaluation should be done to ensure that the junction temperature does not exceed its maximum rating (125°C). Due to variation in individual device electrical characteristics and thermal resistance, the built in thermal overload protection may be activated at power levels slightly above or below the rated dissipation. |
