✅ Use input and output capacitors<\/strong> close to the pins for stability and transient response (values depend on your layout and load).<\/p>\r\n<\/li>\r\n \t
🛡️ For higher current or higher input-to-output voltage difference, plan for heatsinking<\/strong> (linear regulators dissipate heat as (Vin − Vout) × Iout<\/strong>).<\/p>\r\n<\/li>\r\n \t
🔌 Ensure the input voltage is sufficiently above 15V<\/strong> for proper regulation (headroom\/dropout depends on operating conditions).<\/p>\r\n<\/li>\r\n<\/ul>\r\n\r\n
