LM293ADE4 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM293ADE4 is 26V, but it's recommended to keep it below 25V for reliable operation.
  • The LM293ADE4 is rated for operation up to 125°C, but the output voltage and current may degrade at high temperatures. It's recommended to derate the output current and voltage according to the thermal derating curve in the datasheet.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR of 0.1Ω to 10Ω, and keep the input capacitance as close to the regulator as possible. Also, avoid using long, thin traces for the input and output connections.
  • Yes, the LM293ADE4 can be used in battery-powered devices, but it's not the most efficient option due to its relatively high quiescent current (IQ) of 5mA. Consider using a low-IQ regulator like the TLV703 or TPS63050 for battery-powered applications.
  • The power dissipation of the LM293ADE4 can be calculated using the formula: Pd = (Vin - Vout) x Iout + Vin x IQ, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and IQ is the quiescent current.
